Hi eHam Community,
I have a Heathkit HR-10 on the bench which gets very hot around the 6EB8 audio amp tube. It starts to smell like heat in about 1 minute. The voltages out of the 6X4 rectifier are also slightly higher than what is shown in the schematic.
C57: 214 instead of 210
C56: 158 instead of 125
C55: 144 instead of 115
The device receives a little and tunes down the bands.
Is this heat normal? The 6EB8 gets much hotter than the others. I only have the schematic and 3 pages of incomplete alignment instructions.
Also, can someone tell me where Lug 1 of terminal strip Q is? This needs to get jumpered for an alignment. Since I don't have a complete manual, I cannot locate or align the device.
Does someone have the possiblity of sending me this info electronically?
Thanks for any replies.
