Having just thought that the FM Station that I was listening to had another "Technical Difficulty" I didn't give the Silence much Thought, until I turned to see that my ST-70 had gone Dark....SH*T...I turned it off, hoping that the Old Fuse had just had Enough...Well, I dug into it today and started by disconnecting the 360V Leads...Pop!! Goes the New Fuse...Double SH*T..I have read from Curcio's Repair Guide that this means One Thing..Bad Transformer...Oh No!!! Well, I then looked closer, and saw the 55v Bias Lead and pulled that from the Caps...Whaddaya Know...No Pop...Next, I Pulled the Caps and ran the 55v Straight thru the Diode and Resistor...Still no Pop..So then, I put all the tubes back in...No Pop, and now, Glowing Heaters. Hopefully I just had a Bad Cap. I'll know for sure when the New Ones get here...I don't have (2) 100V 47ufs one laying around...I'll let you know how it goes..
I can get all sorts of Mini Radial's from Parts Express...Would (2)100uf 100V do the Trick...Or, can I do Better?...Jeeze, the 100uf's are just .44 Ea....
Well, I did happen to have some Caps laying Around...(2)100uf 63V Gold Nichicon's...Yeah, I Know...Man, they are Small, 3/8" x 3/8"...But They Worked...They will at least hold me till I get some Better Ones. Thankfully it wasn't the PA-060...
