Preamp tubes are 6SL7-GT, used but working (for now - unsure of life). not dead quiet, not noisy - these old octal preamp types can be finicky. the amp sounds good!
This combo was serviced in late 2024. The Jensen C-12R speaker is not original, the handle is not original, was added by a prior owner. Many capacitors and a resistor were replaced, and two ... more

Up for sale is a 1965 Ampeg Gemini I project that was cut down to a head. It's in good condition and works good, but will need a pair of 7591 tubes and a tune up. Obviously, the reverb does work without a tank and the vibrato does not work also, however itt comes with the original footswitch and should be able to get up and working during servicing / It's missing the knobs which is how It ended up with it. They nicely cut down the cab, however no back panel.

Here's a VERY rare opportunity to own a B-15S 15" extension cabinet. Most of the time you see cabinets that were stripped of the amplifier. This was manufactured as an extension cabinet. This is not an orphan cabinet from a complete amplifier. You can see its fitted with the original cups on top that the steel feet would sit in rather than having the shock mounts for the amp chassis. The cabinet is in original cosmetic condition however I am doubting the speaker is original. Its not very ... more

Here's a rarity. An Oliver Uniflex 1x15 combo. I believe this is a B-150 model although its not labeled anywhere. This might be an early build. No serial tag, hand written tube labeling.

This is a great set from when I parted out a bad SVT cabinet.

They are nickel chrome-plated and feature the unique Ampeg head that you need a special wrench for. But don't worry, a standard blade screwdriver fits snugly in the slot and gives you enough torque to fully tighten down your ... more
