Re: Motorola SH21

Thanks for your help. While replacing caps I have run across a resistor that is suppose to be 1k 2watt 10%. It is measuring 1197 ohms. Is this far enough out of spec. that I should replace it? If so, it looks like metal film resistors are the only thing I am seeing in the 2watt range?

Re: Motorola SH21

I understand what you are saying. Is there a limit to how high the voltage of the replacement cap. can/should be? Since the spec. is 25v, is using a 400v or 630v cap. okay?

Upon looking at my original post, I noticed that I forgot to mention that the 5mf 25V non-polarized cap is electrolytic. Will the Mylar as yo...

Motorola SH21

Quick question concerning acceptable replacement capacitor size. The crossover cap. in the left and right channels is a 5mf 25V non-polarized cap. Since a replacement cap. of the same size does not seem possible, it looks like the closest sizes are 4.7mf or 6.8mf. If these sizes are acceptable, whic...
