Parts came in today from ESRC1. Replaced the electrolytics (2) 8mf 450V, and (1) 22mf 450v.
The 6X5GT for $4.00, was an exact replacement for the 6X5G tube.
Powered up slowly with the isolation Variac and no more hum. After a 30 second warm up I started picking up stations. Icon_smile
Reception and selectivity is marginal but volume and tone are good on the stronger AM stations. Next for a recap of the wax paper caps.
Question on tube temperatures:
The Diode tube 6X5GT is running at 223 degrees F.
The two larger 41 tubes are at 260 and 280.
The 7b7 near the transformer is running at 110, the center one at 130 and the right one at 105.
The two XXL tubes are 95 degrees each.
Can the temperature between like tubes be this far off, or do you think I have some resistors out of spec?
Thank you for all the help this far.
