Rated 5 out of 5 by from Great audio performerDoing business with Parts express is a snap, and the product was delivered on time and packed with great care.

Recommendation for changing 12AX7 to 12 AT7 in ART Pro MPA ll 2 Channel Mic Preamp?

This product seems to have better reviews than the 12AX7's from either Rus/Chn or elsewhere. I have not used tubes since the 1960's when they were made in USA while working on USMC Com Gear. The product info suggests interchangeability. Would like some confirmation. Special needs....AC hum/noise, distortion rejection for use with condenser mic applications.
Asked by: GeorgiaDreamer
I have an ART MPA II as well. I've tried a few different tubes. If you don't need a lot of gain, go with a lower output tube. Here's a list of compatible tubes. (100% gain being the highest output)Gain Factor100=12AX7/12AX7A/7025/ECC83/CV400470=575160=12AT7/ECC81/E81CC/CV402444=12AY7/6072A20=12AU7A/5963
