[Drakelist] AC-3 Ver AC-4
Well I installed a heath kit in my AC-4 and all mine does is blow the fuse when the jumper is between pins 1 and 2. I have gone over it many times. Wire for wire reds to reds yellows to yellows blues to blues etc. but it blows the 5 amp and a 6.5 amp slow blow and it blows that also. What I don't know is what capacitors to leave on the bottom there are 2 that go to ground. One from the fuse holder and one from L2 Are these needed? I did not assemble the new circuit board I bought it assembled. I know it is hard to guess without seeing and who knows what kind of goof ups a yahoo makes in wiring but anyone have an idea on where to look next ? It did not blow the fuse before the board was installed. Thanks John AG6GL ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

My power cord from power supply to radio is a little poor looking at the strain relief, and is more than likely a little brittle. Should I try just cutting it off or replacing it? If I was to replace it any recommendations on where to get this type of cord?

[Drakelist] TR 3
I have a tr-3 that I was warming up and the mike locked on. When I came back to a burning smell I shut it down. I found that the transmit/receive relay had melted part of the white plastic shield. I removed the cover cleaned the contacts and when it starts to get warm it closes the relay and will not receive. If I key the mic it locks into transmit mode, I do not think it transmits either. It looks to be over my head in repairing by myself, so I am looking for advice should I keep trying or find some one to repair it? I really like this radio John Gartman AG6GL ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
[Drakelist] TR 3
I just picked up a TR 3 and have enjoyed learning about tube ham radios. I did get a copy of a manual which has been very helpful. I read all the TR 3 posts in the archives and figured out it needed the jumper resoldered on the VFO plug and now it works and it gets better every day. I am going to send it to Jeff in Ohio for new caps and a tune up and have the power supply rebuilt. I do find it is the loudest on 20 meters 40 is good 80 meters is nice and quiet and clear. 10 and 15 meters I have heard people out there but the volume is very low. Is this just the way they work or could it be bad paper caps? Anyway thanks for having this group, I will go back and read anything for the 3 and 4 series to see what else I can learn.
