Report Review for product Vacuum Tube - 7025-WA, Tube Amp Doctor, High-Grade, Premium Selected

You are reporting the following product review:

I have two things to share. First, I received great customer service from Amplified Parts. Second, I own a finicky Super Sonic 60 combo (older version), After tube swapping, I found the two most sensitive tubes to hiss/hum are V1 and V5. V5 may come as a surprise to some, since it further along in the gain staging, but it is the tube immediately before the PI. Putting a TAD 7025 high grade, premium select, in these positions quiets the amp nicely. No more hiss, unless the amp is turned way up, like gigging volumes. Great find!
