running 6V6 in a EL34 designed amp

[12AX7]

I have a amp i built with a output very close to the same as a 2204. I've been running 6V6 in it lately, JJ's to be exact because they supposedly can easily handle the 440 plate voltage. I bias them to about 18Ma and they sound really good. My question is, i run them on the 8 ohm tap with 8 ohm speaker and the POT is 3.2k. I know i should run it on the 4 ohm tap which would be much closer to thier 8k spec. (something like 8k isn't it?) But it sounds much better on 8. Will this be risky and if so what about when running it at home levels? (master fairly low, maybe 9:00 at most)

Then run them on the 8Ω tap.

If you play the amp cranked, take a peek in the back and be sure the tubes aren't redplating. If not, then there's nothing to worry about.

Here's an old thread on a similar topic that has some good information:

I think it would be okay if you monitor the amp like HBP recommends.

Thanks, i will then. They're biased cooler than i see others running them so i assume that helps.

20-22mA is where I had my '67 Princeton Reverb when I owned it. Your bias seems similar, especially if B+ is higher than it was in the Princeton.
