Hello again,
My CL1s-topic is slowing down.
http://www.groupdiy.com/index.php?topic=9951&sid=46ab06f6b9747634612730069a1bfeae
I still need some help on a few things:
I am now sure that there is something wrong with the 350vAC lines from the power transformer. Today I disconnected the two wires coming from the transformer (350v lines). I left the two others (32vAC and 15vAC) connected to the power supply board.
When I power up now the transformer stays cool (not superhot like before). The +15v and -15v output from the board measures +14v and -14v. (Ok?)
The heater and lamp outputs are -12,5v(-) and -33mV(+).
The 325v outputs are of course nothing since I disconnected them.
I have talked to the people at Groove Tubes. They do not have replacement boards or transformers. There has been problems with that power supply. Maybe it would be a good idea to make a separat power board for the 325v?
What I was thinking is that if I put in a second power transformer I could give the board some 350v again?
My question is: would that work? There is space in the box to put in a second torodial transformer if it's not too big.
I need this transformer to feed current for six 12AX7 tubes. Any suggestions?
Thanks in advance.
Richard
