if i didnt have to earn a living i could watch your video s all day its so relaxing and mega rewarding bringing these 40 plus year radios back to l;ife . wish i could do it kind regards mark
Many problems with radios can be just that mal adjustment My rule of thumb with anything not quite right is to do the full alignment procedure this then will usually bring out any gremlins or as you found magically fix the issue I recently did a 121 board that seemed ok albeit a little less sensitive After a alignment it’s gremlins came out to play it developed feed back on SSB RX I did the usual visual inspection replaced a few green caps but still had this issue There was a low voltage on SSB RX caused by a missing resistor on the TX/RX switching transistors took a bit to find and again man made faults are usually the hardest to find Another great video and another classic saved top work as always
I've got one. It was my dad's he bought it back in 1981. He talked to people all over the world on usb/lsb. I remember all it had done was the beep beep put on the anl switch. I wonder what its worth?
Nice set you got there, I just found out my mum sent her colt excalibur ssb to someone to fix as it means a lot to her as it was a gift from my brother who has not long passed away. I saw it the other day i said why it was not on she said it was not working calibration potentiometer is now bent and the knob is missing. I turned it on but no TX power and now no RX. Golden screwdriver once again but she wont tell me who did it. I saw some paper on top of it with a list of things they did/did not do as it is in a state.
@@MicroChipz That's the one 19 inch rack mount like the jumbo but silver i have 3 of them and the gold one the marko excalibur. What i will do when i go down to she her again i will take a pic of the paper and post it on facebook page it is a Fing joke.
bit iffy in the darlington area on solder side as the 121 boards often are when somebody messes with them, they were not made well in that area, not an expert by any means but very fermilliar with this circuit board, and as some say the better 125 board, ask me about a cobra though and i wouldent have a clue lol
Hi MicroChipz, Can you Please Help me, I own this same radio, I can,t afford to send out for repair, There is know one in my area, I was given this radio My a older gentleman, He was I guess, going to have it run on 10 mm also, You can tell theres been work done, Bad solder work also.In your Video you show wires crossing the crystal plug in, thats were The 10 meter Crystals are supposes to be, am I right, The Problem I have is the radio ,Has speaker noise but no signal on receive or transmit, Is that because i have to put those wires across the Crystal holes. Please any help would Be Appreciated, I just want a ssb radio to work at home to listen to, Thanks Brian
Hi , I would strongly recommend you get it to a tech , you might be trying to chase a fault that’s not there , or if it has a fault without replacement parts you won’t get it going g again .

I recently did a 121 board that seemed ok albeit a little less sensitive
After a alignment it’s gremlins came out to play it developed feed back on SSB RX
I did the usual visual inspection replaced a few green caps but still had this issue
There was a low voltage on SSB RX caused by a missing resistor on the TX/RX switching transistors took a bit to find and again man made faults are usually the hardest to find
Another great video and another classic saved top work as always
Thanks Andy :)
Another great video from the calmest engineer in the business.😄👍
Its not all calm believe me ;) This radio did test my patience a bit but we got there in the end.
Superb video
Thank you so much 😀
Hiya mate that has been hacked up well but i'm sure once you work your magic it will look good looking forward to part 2 tpo video as always
Thanks Andy

Well going off ebay prices at least 150 maybe more if good condition.

Opps sounds like it’s had a rough ride .
@@MicroChipz She wont tell me who fucked with it.
