Power transformer for tweed deluxe / princeton reverb
« on: February 21, 2013, 03:42:53 pm »
Hey guys! (first post here, but a long time reader!)

I have a couple of transformers that where meant for a 5E3, but since I got one already, I decided to build a princeton reverb.

The specs for the PT are:

Primary: 230VAC/50Hz
Secondary: 325-0-325@70mA; 6.3v, 2A; 5v, 2A

At first, they seemed a little underrated, but then again, the Princeton Reverb with it's 4 12AX7, 2 6V6 and rectifier uses the same PT as the Champ, with a single rectifier, Power tube and preamp tube.

And the specs on this transformer as this other one I found for sale (and this one is sold as a Princeton Reverb transformer...)

What do you think?

Cheers!

I'd use it on a PR.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Then again, those PR PTs were underpowered. I'd prefer to use something with at least 100mA rating on the HT winding - especially if its a 230V/50Hz mains PT made 'offshore'. Depends how long you want the PT to last I guess.
A bus stops at a bus station. A train stops at a train station. On my desk, I have a work station.
