micro-amp SE with 2,5k OPT+

boergars · 10th July 2007, 07:19 PM

Hello everybody.

I have bought a few (4) SE output transformers 2,5K/8 and max 3W.
Is there any good ideas of output tubes that can handle these?
Looking for a cheap solution, so no 2A3.

Sincerely Per

50c5/12cw5/6cw5, (7 pin miniature) or the octal equivalents, 50L6GT and the like. There are a lot of small radio output tubes that are designed to run on low plate voltages ( 120-160vB+) that need a 2.5k primary.

Hi,
I recon 5842, 6C45pi, 12B4 are suitable. they gives 1~2W per tube.

Cheers

My vote is for the 6c45pi. I find that I can get by with this with my
cd player with no preamp. There is a Tiny Apmpifier thread on our
tube forum to look at too.
