RE: 20B fun without Nreaking the Bank...




I am going to have to agree here with Jeff-Dennis

If you have a low-mu tube you will never get the dynamic quality (dymanic contrasts) it will sound like all other SE amplifiers limp whet noodle?


I discovered this 16 years ago with my then WE 300b tubes and tube amplifier these low-mu 6sn7 tubes just dont have the getup and go like a higher mu 6sl7! or other higher mu tubes.

once you discover this for yourself you will never look back

I am speaking from experience here just like jeff and Dennis

my current SE amplifier uses a very hi mu tube 300!! LED biased and the gm70 final tube is also biased with LEDS!!!


Now there is nothing wrong with LED Bias actually if you look into why you will see several advantages one i will mention here is when you LED bias you get to full mu of the tube! and you remove rk bypasses and the rk!!!

Have a blast i am
