okay so off of one side of the 6.3v heater run a 100ohm1/2watt then at another point from the OTHER 6.3v heater run another 100ohm 1/2 watt YES? then I should be good?

Love Curran

so can I tie the 9 pin too ground with a 100ohm 1/2watt resistor then and not goof up the circuit? I have BOTH heaters in the correct pin configuration BUT do I need to ground EVERY tube socket with a 100ohm? sorry too be so high maintenance BUT I am very new at this adventure!! Love Curran P.S. tha...

no, there is nothing going to ground off of the pin 9 sockets now. I took the 5 pin heater lead and moved it too the 9 pin. I jumped the 4 pin heater to the 5 pin as well. and the Jacks in the shots are the FX loop jacks and speaker jacks outs. and you can see that off of pin 2 there is a white wire...

here are the there sockets

okay, I did the Mod and removed the 9 pin ground from each 12x7 socket, then I moves the 4 pin filament heater to bridge the 4 and 5 pin. moved the 5 pin filament heater too the 9 pin. NOW I get a very load hum from the amp. when I go to turn it off or to standby thought the amp starts to play sound...

well from what I am finding out about the amp I think I need to perform a wiring mod to the preamp sockets. BOTH filament leads for each socket are running to pins 4 and 5 with a ground wire coming off of pin 9 this is for the original 6N2P preamp tube that these are wired for. the mod says too remo...

thanks I will try the tuner kleener. I did not do any rewiring as the red bear fan site said it should work fine going from the 6H2P-EB tube to 12ax7's in the preamps. and the power section already had 5881's loaded in it from russia anyhow.

thanks

Hey Everyone. I have a really neat red bear MKE60 that I won on ebay and re-tubed. before the re-tubing it had the ORIGINAL weird Russian tubes in it. I order the US replacements(12ax7's and 5881's). I got the tube swap info from a red bear fan site. NOW the output of the amp is whisper quiet. I can...
