Title: Power transformer for tweed deluxe / princeton reverb
Post by: polymolly 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.

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.
