DSL100H - EL34 replacement and BIAS settings



I'm going to replace the power tubes with a new kit of 4 matched EL34 and I would like to know what is the BIAS setting recomended by Marshal in terms of how much mV we should adjust on the reading of the Test Pins  CON5. I found someware that is 90mV per side, but also other different info (some guy said 76mV after consultation with a techician). Please could uoy kindly advice?

Hello Roberto,

Regarding your question, if your DSL100 has the high/low power switch on the back then the bias is 80mv per side, we reocmmend that the bias is set by a qualified enigneer. To find service centers in your area please go to our website www.marshall.com and click on local retailers.


Kind Regards

Marshall Support
