1970's Ampeg GV-22 Transformer Specs
« on: October 09, 2024, 03:31:13 pm »
Hey everyone!
Came across an old Ampeg Gemini GV-22.

The original OPT is toast. I'm wondering if anyone might know what the original specs for these transformers were? (primary impedance).

Hoping to find an equivalent that is less expensive than at fliptops/mercury.

Thanks all!

I don't know the exact specs, but looks like it claims to be a 40 watt amp using a pair of 6L6's fixed bias at around 480 plate volts.
Something like an 8 ohm Super Reverb or Bassman type replacement would work fine.
Around 3500 ohms or somewhere in the neighborhood.

Correction - it looks like it has 8 and 16 ohm taps.

You need 16 ohms and 8 .
This Hammond 1760 L will work , check for measurments
