Friday night I got the VHF tuner dialed in had to adjust the slugs for each channel plus the hidden master slug for CH13 and a coarse osc adjust trimmer. The procedure I followed was to start at 13 making the coarse adjustments to give it enough range and work my way down the channels.
I started. By going the other way and made things worse before making them better.
All but one channel has good sound color and monochrome alignment on the fine tuning and all channels optimum fine tuning is in range of the fine tuning control...I would have liked to line up the osc so each channel is the same position on the fine tuning but that isn't easy especially with my body position effecting reception and affecting it differently on different channels...But it is good enough that it should work well on any VHF channel I'm ever going to pipe in to it and that's all that matters to me.
Last night I took a crack at making the UHF tuner work....it will tune in everything from 13-35 on one position of the UHF tuner and nothing elsewhere. Since I don't use a UHF modulator normally and only wanted to make the UHF channel indicator match the tuner position I decided to leave it alone.
I also removed the safety glass and trim and cleaned the rotten rubber gasket gunk off the bezel with isopropanol and off the glass with goof off. I then polished the bottom of the brass trim with brasso and steel wool and sprayed lacquer on it. I reassembled it upside down to hide some small dents and and minor color difference on the bottom. I may go back and hit a couple spots on the side which I notice more now that it is back together. I'll post some pics of the cleaned up trim/safety glass later.
All I need to do now is convergence and reassembly.
Once that's done I'll go back to my Moto 21CT2B and order the tubes the other CTC4 chassis needs and some slip plate to replace the silver foil that has peeled off it's CRT shroud.
That all has to wait for the folks to release me from work on the enclosure for our covid19 anti-starvation garden...
