Re: Very Inexpensive 7623A, but Problems


Take LOTS of pictures. The harmonica connectors have many different voltages on them as low as 5.5 to as high as 130. I quicky turned a 7603 in to a parts unit one when I switched 2 of them. Sent 130Vdc to all the wrong places. Ended up with too much damage to save it so now I at least have a spare CRT.

I came across this video ( and it shows something that looks very much like what I am seeing. The caption, just before it shows the radiating twisting traces says "This is how it looks with the defective capacitor inside..."

This fills me with hope.
