If you have any expertise with a Gonset GSB-201 amplifier, pleas lend me your insights. I am getting a Gonset GSB-201 that has modifications. I don't have it yet so I don't know the extent of what wa

If that 50k resistor is the bleeder on the power supply, * leave it alone * !!! - Jim WB6BLD _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contest

2100v is too much for 811As. The HV PS power supply's regulation can be improved for SSB by resonating the filter choke at 120Hz with a cap. However, for AM there is no benefit. Another improvement i

The paragraph above stated " I am getting a Gonset GSB-201 that has modifications. ........and the HV choke input filter choke is missing." There is no filter choke left in this amp. I can only confi

You still need a bleeder resistor to avoid premature aging. I have seen the carcasses of 2 GSB-201. Both had suffered violence of some sort and been partly dismembered prior to viewing. I was not abl

To discharge the filter caps after you turn off primary power. A few second time-constant is usual. As you surmised, this is an issue separate from the minimum-current aspect of a chok-input filter.
