Default Hammond 125 ESE amps for 2018 10 5 post

there was a post from 2018 10 05, but it's gone now. Poster was looking for help with Hammond 125 ESE.
Here's some info which may help.

I'm using the Hammond 125ESE in a PSE 6BX7

I like it very much, but it took a few months for the sound to improve.

Here are some that use this output transformer:

The circuit shown by Chris is from Angela Instruments a few years back. Anyone thinking of building one should be aware that the 880 ohm resistor on the cathodes of the EL34s is wrong. Change to a 470 to 500 ohm or you'll be running the tubes too "cold".

When this circuit came out the biggest Hammond, without going to their "mega" iron was the 125ESE. Now there's a FSE and GSE. Might be a worthwhile upgrade.
