If you want the job done right do it yourself.
I purchased a GE 810 restored and working, only to find the soldering and terminal work sloppy, messey and quite ugly.What caught my eye was the modifications, a whole mit full of extra parts around the horizontal output socket, the poor soul must have really fought with the bias circuit, albeit the set
worked but how?. My instinct was to check and verify that the tubes are the correct ones, well the horiz out is a spanking N.O.S. GE 6GB6, but wait a minuit
this tube has all the pins connected on the base, the schematic and my RCA receiving tube manual shows a 6GB6 with two pins not connected and on the tube base. When you have a manufacture that saves money and space by using unused terminals on a tube socket for a convenient hookup post and a revised tube is installed you can see where this can go. So i reduced the part count to what the diagram called for and put in an earlier 6GB6, suprise suprise the average plate is current RCA tube manual text book perfect. a quote from Ronald Regan "Trust with verification"
my quote "Get your hands on a RCA receiving tube manual!".
