<< < (3/3)

RPP:
It's a short list:

62 x 22uF/35V SMD caps replaced with 62 x 22uF/50V Nichicon UHE radial caps 

EDIT: 63 x 22uF/35V - I found another one on the front panel board when I was troubleshooting . . .

My unit has Option 2 installed so there are 2 extra boards to support the 2nd channel output.  Example of a radial cap replacing an SMD cap:

Why not replace with SMD capacitors? Preserve the originality  :)

RPP:
Radials are easier to retrofit, IMHO.  The original caps leaked and destroyed parts of the boards . . . don't want to keep that part of the originality, just the function,  lol.

imo good call on the THT parts being used instead of more SMT. Bet they will last longer because its isolated from the heat.


Hah, I wonder how much life you can get from a cap if you use heatsink clips on it during assembly.

I need to do a TDS 1992ish~ 4 channel tektronix oscilloscope with all caps and the AWG2020. year of the capacitor it looks like
