HI
The Power Transformer is labeled UTC R4, I checked it with my ohm meter and got the following
Primary 3.2 ohm
Sec .4 ohm
Sec .4 ohm
Sec 156 ohm
Out Put Transformer
input 95 ohm
Ground -> 4 ohm lug = 1 ohm
Ground -> 8 ohm lug = 1.2 ohm
Ground -> 18 ohm lug = 1.7 ohm
Filter Choke 162 ohms
At least nothing is shorted or open
I see now on the SM that KT66 is the correct tube, You think someone not knowing any better thought that any tube labeled with 2 sixes would work ?
Do you think the Power Transformer is correct for this amp ? I see the Heathkit part number is 54-32
Thanks for any help, This is my first adventure into tube land.....
EDIT
After more research I now know that this transformer is not correct, Bummed out now...Any suggestions for replacement ?
EDIT #2
After more research it looks like the pinout of kt66 and 6v6 are the same. Just looks like the KT66 is a more powerful tube more current flow and higher voltages. If my Power Transformer is working correctly then I should just be able to get new tubes.
EDIT #3
Not knowing what other mods may have been done it might be prudent to disassemble the entire amp and put it back together, I was planning on replacing all resistors anyway might cost another $11.
Any thoughts out there ???
