I had a TR7 about 15 years ago and loved it but I sold it to help finance my K3 purchase, which I also love and still have.? I acquired a TR7 today from an estate today with the PS7.? It's S/N 2713. The thing was pretty dirty and will need a case repainting but seemed OK otherwise and the price was right.? Here's what I have gleaned so far:
1.? The PS7 doesn't work.? I hear the transformer thunk when I turn on the rig and the fans on the PS and TR7 both come on but nothing else.? The fuse is good and not blowing so I'll need to fix that at some point.
2.? The rig came on fine with a different PS and seems to RX and TX fine but power out was around 170 watts and the ALC light was not coming on.? I adjusted the control on the ALC board to about 150 watts on 20M at full drive and the ALC light now works but stays on no matter how low I adjust the drive.? I know there's another adjustment for that on 10M on a diffferent board but I haven't gotten to that yet.? Power doers adjust down to zero now.
3.? The S-meter reads very low but signals sound fine so guess that's another adjustement I need to make.? Forward and reflected hardly move the meter and adjusting the controls by the antenna socket make no difference.
4.? Some good news is that all 4 filter slots are full which is great news for a CW op like me.
5.? There's a big change in noise between USB and LSB looks like carrier balance is off.
6.? The sidetone volume level is very low, I have to turn the volume control way up to hear it.
I do have a PDF copy of the service manual.? The big question is will I need the board extenders to fix all this and properly align the rig?? If so wheer can I find some that won't cost me too much?
My apologies in advance for the many stupid questions I'm sure I will ask as this project moves foward!
