Is it possible to purchase el 84 quads that will bias up correctly in a Peavey Classic 30 combo? I think plate voltage is 330-350 volts. Thanks!

Absolutely! These tubes should work very well with a Classic 30.

Product Reviews
Tested these tubes against TADs and JJs in a home-built amp with a preamp based on the JCM800. These have a clearer distortion sound, if that makes sense. Also these have notably more midrange and smoother highs than the TADs and JJs. I highly recommend these for any EL84 amp in which you want to get a smooth power amp distortion sound and get clarity without harsh treble.
