Something I forgot to mention is that before disassembly I took lots of pictures with my new Galaxy tablet for reference. It will focus nice and close up.

Now to attack the underside. I made up the little stand so as to not crush the tubes and such while working on the circuit.

After reassembling all the trimmers , grid cap wires, replacing some bad resistors along with the power filter caps I did some rough alignement. I used a signel generator a 456k for the IF. It tuned up pretty well but I found it made some miner poping and cracking noises when powering up. Also the audio sounded a little garbled. So after some capacator replacement all around the detector tube it work much better. I am disapointed that it has no automatic vol contol.
