If you have an AMPEG amp that is over 25 years old, you should consider replacing the filter capacitors (shown here is a 1970s V-4B). Re-capping will restore punch and clarity to bass frequency notes as well as rid the amp of background noise. I offer such service for $90. I use high quality capacitors (low ESR and high ripple current ratings) that are higher quality than the originals. While I'm in there I do a complete diagnosis and overhaul at no extra charge.

BEFORE and AFTER: I convert Fender Reissue amps from PCB (printed circuit board) to point-to-point circuit construction. This makes a huge difference: it gets rid of all noises associated with reissues and gives the amp a beautiful early-sixties Fender vibe. Depending on model price ranges from $350 to $450 (includes new potentiometers, jacks, capacitors, and resistors). I use a non-conductive. high-quality epoxy board to attach wire-to-component points.

I had a request to build a pair of Western Electric WE-91B monoblocks (the finished project shown here) based on original specs. The WE-91B were used in movie theaters during the 1930s and are triode-based class A amps putting out a very loud 8 watts. For these replicas instead of using electrolytic capacitors I used audiophile-quality poly for cathode bypassing and resin-filled motor run caps for power supply filtering. These motor caps are rated at 1000 vdc and don't even break a sweat in this application. Other caps are vintage oil-paper. Tubes are NOS RCA 6C6 pentodes, 274B rectifier, and 300B power triode for output. The transformers and chassis are spec'ed exactly to originals. These also sport balanced inputs, again, like the originals.

ToneTron Amplifiers Tweed 40 is voiced especially for steel guitar and also works great with Telecasters. This one is on its way to its new home in London, UK.

Silvertone/Bell & Howell Conversion: I took the power amp from a 1961 Silvertone tape deck, added a preamp and tonestack suitable for guitar, and mounted it inside a 1950s Bell & Howell speaker cab that spend most of its life in a storage closet of a research facility (thus the speaker is in excellent shape). It sounds similar to a tweed Princeton with no background noise and a little more growl. I'm going to sell it for $300. If interested, contact me.
