Hey all,
I have been trying to restore these chassis myself and have been doing good but I have hit a wall on this one and have not even started.
Some lazy person decided to recap this radio without re-stuffing anything.
They soldered everything on top and even cut off a few terminals.
First is 4989-AK, I am using 4989-ODG and it calls for (2) .09 or .1 caps at terminals 1-3 and 1-5. The problem is that the person cut off terminal 3 so there is nothing attached to it. then he overheated terminal 5 and it detached from the block. that I can deal with but when he fixed it he only put on one .05 cap from terminal 1 to terminal 5.
Do I just do what they did since he probably jerry-rigged something?
7625-H is a one .006 cap. I am using 7625-SU and it says terminals 1+3 but terminal 3 is clean and not used. Only terminals 1+2 were soldered to?
What di I do there?
Next are the electrolytics, one 8 and one 4. Is it bad to replace with 2 10uf's or should I use a 10 and a 4.7
They used 2 8uf caps and I cant seem to find which should be the 8 and which should be the 4. Still not reading the schematics very well.
Last is the .01 bypass condenser. Can I just put in a .01 cap?
