Marshall TSL: 3 pins connector for bias setting.
Hello everybody !
I have a unique JCM2000 TSL602 "cutted Head" (the combo was cool, but I prefer to transform it like a head and plug it into a 4x12"... that's why I say it is a unique head !)
I have seen on the rear pannel, next to a trim pot (for bias settings I suppose), that there is a 3 pins connector
Are these pins here to connect a bias control unit ? Does anybody know if it is possible to check and set the bias with a simple multimeter connected to these pins ?
If yes, how should I connect the multimeter ?
I will change the EL34s for 6L6s, so I will have to set the bias correctly. Maybe that this connector will save me...
Thanks a lot.
