brentrocks Posted April 24, 2013 Posted April 24, 2013 I tried a set of NOS GE 6L6s in my Chicago Blues box tonight. I also put a NOS rectifier tube in it. The CBB amps have internal bias pots, so i hooked up my meter to see what kind of voltage the stock Sovtech tubes were running....503 volts. After installing the GEs, i bumped the bias up to 515 volts...i figure the NOS tubes can handle it. There is a very noticable difference in the tone...the cleans are a lot clearer. The amp is a lot more pick sensative, notes ring out much fuller now. Here is the amp.... The Tubes....

Guest HRB853370 Posted April 24, 2013 Posted April 24, 2013 How does one find NOS tubes? Take a trip to Russia!!
schundog Posted April 24, 2013 Posted April 24, 2013 Finding them is easy. Finding working ones is harder. Finding working good ones is harder still! So, in other words, many NOS tubes are actually POS?!
