Ive been working on a 457 here and there. Recapped it including the tantalums. Started to do the alignment and found there to be 16 volts out rather than 13.8. Pulled the regulator and it tested fine. Ended up being a disc capacitor that had a 2k ohm short across the 2sc1618 base to collector...

I have this radio and Im pulling out my hair with it. I only have the sams for it and I m having the wierdest problem with voltage getting to the driver and final. These voltages all appear correct. The transmitter gets its voltage from #1. The next part shows #1 feeding a diode going up throgh...

No schematic but I think that these were badged under multiple names. The tuning can slugs are painted in place and removing them is a real chore. The threads often strip when trying to soften the paint. I triedcto slign the output and wound up with the sliding slug issue i fixed that with a...

My superbase is dead. Nothing but static, no tx, no rx. I havent started on itbyet but did do some research over at grumpy's. I readcthat the superbase was notorious for leaking caps and the goo eating runs on the board. I did notice a crystal with 3 leads. Never seen one before. Does anyone...

When I got this radio, it was receiving fine but had an intermittent transmit problem. When I decided to reflow the board, I lost everything. Now I hear a faint and untunable USB channel on all 40 which tells me ive screwed up my vco or pll. I have another 555 that has no receive, transmits...

I was able to get most of the radio transmitter working but still have some issues with the transmit. Im getting a 2w carrier on AM and 4W peak. Pretty sure that I should have a better carrier on AM than 2 watts. On SSB, I get 2 watts full whistle on both USB and LSB. The7558 is new and works...

I have both radio sets. There are some similarities but also a lot of differences. Im hoping that people who post here will keep the thread about the SUPER and not the DELUXE (sams cb-19). Im looking for anything about the super. I need to fix a few weird problems. CBTRICKS has a relabeled copy...

I know, I know. Not another galaxy thread. I did try asking through an old thread but got no response. Firstly to minimize redundant comments, I am a radio technician military trained. 22 years service. Lots of know how in repairs and restoring. All adjustments as per service manual done...
