Hi

Thanks for the help  :cheers:

Yes the last one on the photo is a 18K

But i only have one 18K resistor  in my old parts box, and no 18K in my new parts boxes  :cry:
I have also looked on old china chassis, I might have an old CRT TV in my garage that i can take apart tomorrow, to see if there is one more 18K 1W or better a 36K 2W resistor

Hi

I did not have any matching resistors in my parts bokses, or the old CRT TV - so i have to wait until middle of the week to get the last fiexed on the monitor.

Meanwhile i want to change the caps on the other boards too.

Starting with the motor amp board -> diagram can be found here: https://www.dropbox.com/s/a8ekyt9iepimzmx/Motor%20Amp%20PCB%20%28802%20KB%20PDF%29.pdf?dl=0

It seems a bit funny, there is to capacitors in series. 2x 100uf 35V
I want to replace them with some new, I guess that the two new, that I install need to be connected they way as in the picture, and also the polarity is correct, as i show in the picture?

Update added som ned photos of the caps - it seems that they not are original, they are solder to an resistor, and a diode

Also the other cap C30 at the right side, do I have marked the polarity correct?

Update

Put in new caps on the board - including the two weird ones, also noticed that they had the two positive leads solder together and the negative leads to the diode and the resistor, so I put in the new one the same way   ;D
