    Hey guys,

    I replaced my Tung sol 5881's with Ruby 6LGCMS's that were recommended by magic parts.

    My plate voltage is 364, so with the 30W rating my 70% came out to about 60 mA. The issue is, that I turned my bias adjustment all the way up and it's maxed at about 42 mA.

    I was wondering if anyone could lend me some input. Thanks!

    All of the PRS amps I've dealt with are 30mA +/- 5mA

    Same here, but my amps are the single channel HXDA and DG30. I’d check with PRS.
