Ok I have read and poked around, then read some more, and poked some more and read and looked over schematics and poked, and you get the point, and at this point realize im in over my head a little when it comes to sweep tube gear.
I was freely given one very old d and a phantom amp. It is the 12 tube 6lq6 version, with 3 relays, and the 12aq5 keying tube. I know the high / low relay part of it has been blown apart, but it is stuck in high mode. Not a huge deal to fix. and since it is working, except for the meter on the front, is not a huge concern atm.
I am really wanting this to work on SSB, and it will as long as you keep making noise, but let the carrier drop, and the relay never seems to want to re engage. It works fine on AM and works fine with CW, and works fine on SSB as long as you keep the modulation going. All the tubes test OK, and I am getting around 600 on 10m so I tend to believe the tester as this seems in line with what others are getting.
What I am wanting to do is to give it an acceptable SSB delay, OR replace the keying tube with a tip type transistor, such as the 10 tube versions carry. OR replace all the relays with 12 volt versions, which would still involve getting rid of that pesky keying tube. Has anyone thought about this or done this in the past? I have a perfectly good 12v transformer, and a rectifer circuit to provide for the relay keying.
Another thought, there is a RCA jack on the back that i "thought" would be hooked to an external relay for keying , such is commonly found on other amplifiers. However this one does nothing. According to the schematic, and poking around, it is connected to the standby switch, and then to ground.
Any help from anyone with more experience with these amps than I do? If I left out anything, I will be happy to supply additional information.
