That said, thats not uncommon with most small-wattage amps, and it certainly doesnt mean that the amp isnt touch sensitive. The Eric Clapton Crossroads Stratocaster guitar, or Sun Strat will be produced in a limited run of 100 instruments globally; the Crossroads 57 Twin-Amps will number only 50. The12AY7 will work, however, so some owners will buy one and stick it in their amp. The sweet sounds that come as a trade-off are well worth it, though. This tranny is comparable to those found in Deluxe amps from the brown era through silverface. Morning came with a whining voice delivering a plaintive wake up call Its got to be something stupid and simple. Inspired by a huge steaming mug of Jamaican High Mountain meth, we sat back down at the bench, tilted the innards of the Deluxe chassis forward beneath a bright halogen desk lamp and peered in for answers. We worked with Mercury to make a few tweaks, and soon we were positive we had the right transformers. One of the vendors we contacted was Mercury Magnetics, whom weve worked with in the past They sent us five different power and output samples, each based off an original transformer set found in a vintage Deluxe amp. Once again, we asked the prescient Mr. Valco for some Hoosier insight: The impedance mismatch in this particular amp using the 6L6s is really not a big concern, it wont hurt the amp and will either sound good or it wont. This limited-edition amplifier features a custom engraved commemorative Crossroads 2007 badge autographed by Eric and his Crossroads Antigua graphic is artistically embedded on the grill cloth. The hotter transformer in our Super Lead produces a comparatively higher and less compressed distortion threshold, and if not for our pair of NOS MullardEL34s, we might need to be more selective about choosing current production tubes that can withstand +500 volts on the plates. Of course, the perfect segue would now be to decipher the special nature of the original output transformer in Neil Youngs narrow panel tweed Deluxe, providing you with a timeline in which these happy accidents appeared, or better yet, a source for clones of thee special gems via, say, Mercury Magnetics. And womens hands tend to be smaller, making it easier for them to run wires and solder connections in the tight confines of the amp chassis. We could easily live with either speaker, and the Deluxe also just kills pushing our 8 ohm 412 pinstripe cabinet. Our amp measured 522 volts, while the plate voltage on most post-plexi 100 watt 1959 amps are usually loweraround 460 volts. On some small 6V6 amps, using 6L6s can and does cause the power transformer to run hotter because more current equates to more heat. A search of previously completed auctions revealed that vintage AC50shad recently sold for anywhere from $900 to $1600 (more for the earliest, small box candy panel models with tube rectifiers). In the beginning Fender paired small combo amps with lap steels and electric guitars aimed at student players, but word of the superior tone and build quality quickly spread among professional musicians. As Neil Young described, bringing the mic input volume up with the instrument volume set between 6-8 gradually deepens the tone while slowly igniting an intense explosion of thicker second order harmonics and distortion as the dynamic character of the amp softens. Its also a lot more expensive. But, like tube practice amps of yesteryear that needed to be driven and played hard to achieve their fullest tonal potential, it can require a more dynamic and forceful touch to tap into its inherent dynamics. The Deluxe does not discriminate between single coils or humbuckers, ravaging both with equal fervor, and the responsive dynamic character of this amp simply is not of this world. Each guitar will be crafted to Claptons specification and bear a unique Crossroads Antigua graphic designed and originally hand-drawn by Clapton himself. These changes dont really affect tone, but they do reduce hum and improve playability.

I dont know the training regimen off hand, but I believe many of them cut their teeth on guitar wiring before moving on to amplifiers. Good Things Small Packages The tone, the vibe, the drama of this amp is stunning, and it left us wondering why the vintageAC50 gets so little respect. NewVolt Automotive Amps. Excellent power, punchy and fat with exceptional clarity and tone. IT imparts an intense, throaty tweed character with enhanced mid and treble presence, remarkable clarity, and an authentic vintage 50s vocal tone with softer bass response and slightly less volume and power than the Deluxe 18002. My old Deluxe might have been built with some different stuff than yours, even though they were both stock 1957 5E3models. In the 20 watt wheelhouse occupied by the Two Fifty Nine, it has no equal by a mile. Digging deep into the Junior, the Vox responded as the twin EL34s became fully inflamed, gorging on 430 volts. The amp just didnt sound right. Its not a sound for everybody, but it speaks in the raw, unadulterated tones of no-holds-barred slingers of the first classic heavy rock era. The busted-up sound of the Tremolux above 56 is gloriously righteous indeed, but with more clarity and less provocative intensity than the Deluxe.

Most Fender amps used power transformers that could handle some extra current demand. Mercurys ToneClone+ Output Transformers give players more impedance options like alternate and multi-tapped secondaries. Kicking in the Gain Boost adds a dose of rage to the tone, and I thoroughly enjoyed playing quick double-stops and soaring country bends with the SE Minis overdrive-infused, high-midrange snap. Our thinking was, not only is the 12AY7going to be tough for us to get in quantity, but many players in fact prefer the 12AX7s higher gain. Obviously, we use new parts, not 50 year old stuff from a flea market or whatever. Why should guitar players care so much about the transformers in their amps? Sounded like shit. The single-ended, all-tube head is powered by a Sovtek EL84 coupled to a JJ ECC803 preamp tube and a Mercury Magnetics GA5-P power transformer for a maximum of four watts.

Buy if For example, Alexander Dumble told me he likes our new 57 Deluxe, and was surprised that we used such heavy wire in the chassis, as its really not necessary. If there is a large drop it means the transformer is having trouble supplying enough current for the 6L6 heaters if given enough time with the 6L6s could damage the power transformer. Decades ago, practice amps were effectively no-frills versions of their bigger brothers. An impedance switch could be wired (I use a blackface grounding switch) as a power tube type selector for an 8 ohm speaker to go between 6V6s and 6L6s.

Well, weve been here before, so we made a call to Gods Country and the Columbus, Indiana domicile of Terry Dobbs Mr. Valco to you. Its pretty well documented that Leo Fenders some times changed components on the fly, while the official schematic documentation would be updated later.

It has just four controlsGain, Tone, and Master knobs, along with a tiny Gain Boost switch. Notice you always have an 8 ohm option with both types of power tubes. Could we safely run the Deluxe with 5881s or 6L6s if we preferred that sound over 6V6s? We could mine brilliant clean tones on 3 at a usable volume level that revealed all the gorgeous detail of the vintage patent number pickups in our Historic Les Pauls, and our Stratocaster, Nocaster and Les Paul Junior all sounded equally good. I use the TO26 in the Allen Sweet Spot, Accomplice Jr. and Hot Fudge with Nuts amps with excellent results. TQR: What are the unique challenges involved in building hand-wired amps, compared to those with a printed circuit board? Expect the unexpected and coolly deal with it. Wed ease into 10 on the volume controls later. With the volume backed off to 4-5 a bluesy jangle emerges anchored by solid low end, rich midrange, the sweetest treble tones imaginable, and variable levels of sustain and edgy distortion that can be controlled both by the volume on the guitar and pick attack. Taken in context, what were suggesting here is that in our experience, the Deluxe has no equal as both a Fender and Marshall style 20 watt rocker (depending on speaker selection), and well add blues to that description equipped with 6V6s and the Jensen C12N. As it takes the most watts to reproduce the bass, you notice distortion there first, and since Fender-type amps are so bass heavy, you can quickly hit the wall with headroom, so a noticeable increase in clean bass response certainly feels like a more powerful amp with the TO26. The Crossroads platinum package is highlighted by the Crossroads Edition 57 Twin-Amp the perfect sonic companion to the Crossroads guitar. Need a dash more mids? Hit the low E string on a fat E major and it holds. And the ComponentsF&T filter caps, Alpha pots, Orange Drop capacitors, carbon-comp resistors, two Xicon power resistors, and a Cliff input jackare all top-of-the-line.

Turned out that the value of the bright cap on the Vibrato channel had been changed on the Vibroverb, rendering a thin, scalding tone that would have given Ed Jahns fits, as it did us.

Wouldnt have crossed our mind at the time. The baffleboard swap and added switch on the tremolo intensity control were clues that someone had also spent time troubleshooting the amp, probably trying to detect the cause of the Pros weak output, thin tone and curiously harsh edgy distortion. The pathway to recovery is founded on the movement toward a change in lifestyle. We acquired a 115 blackface Pro, and while it ultimately proved to be an extraordinary exceptional amp, we were also reminded of the potential pitfalls that exist when buying old amps sight-unseen, as well as the potential rewards.
