How can the chassis be electrically HOT if the chassis is tied to ground. Either you've lost the ground connection via the power cord or your electrical supply i.e. the plug is not wired correctly what ever you do...

[Drakelist] low plate voltgage l4b
I recently aquired a l4b. I upgraded the ps and soft key with harbach. I turned the amp on in ssb with no load and have 2400 volts. I did not try and key or do anything else as i do not want to cause damage. I believe i should have 2600volts. 73 marc hs0zju sent from galaxy tab 10.1 ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Marc, What is your line voltage? 73, Lee -Original Message- From: hs0zju hs0...@gmail.com To: drakelist drakelist@zerobeat.net Sent: Mon, Feb 20, 2012 10:53 am Subject: [Drakelist] low plate voltgage l4b I recently aquired a l4b.

Re: [Drakelist] low plate voltgage l4b
Marc - I just rebuilt the L-7PS with a Harbach board (and a L-4PS with the Heathkit Shop board)Both boards show 2700 volts on the amp meters after putting them into operation. Did you do a low-voltage test before installing? I applied a 20VAC voltage to the input and got ~50VDC at the outputs verifying the voltage doubler function. You may want to give that a trysounds like a part reversal during install. Dino KL0S On Feb202012, at 1050 AM, hs0zju wrote: I recently aquired a l4b. I upgraded the ps and soft key with harbach.

Re: [Drakelist] low plate voltgage l4b
Typically this is due to low line voltage or a HV meter circuit that needs to be recalibrated. 73, Evan, K9SQG -Original Message- From: hs0zju hs0...@gmail.com To: drakelist drakelist@zerobeat.net Sent: Mon, Feb 20, 2012 10:52 am Subject: [Drakelist] low plate voltgage l4b I recently aquired a l4b.
