Help a newbie out with his Sherwood S-800iii

[vandalfsens]

Played wonderfully for several hours. Now a weak right channel, very weak.
Is there something easy/ cheap I can replace on my own to troubleshoot?
Is it likely a tube issue or is it all the wiring underneath?

I'm a moderate DIY'er in general but I've never soldered anything or done any type of testing...

You need to understand that if you make a mistake it could be fatal!

The voltages on your system are High, and will possibly remain charged up after power off.

Your fault could be a bad coupling capacitor! If you want to do this your first thing is to get and post a circuit diagram! If you are not confident don't take a chance!

Do not do any work on the system until you have read the safety advice on the forum!

Hi Vandalfsens,

You need to be sure the fault is in the amp.

Swap over your source leads to see if the fault moves to the left channel.

If this makes no difference then swap over your speakers leads.

If the fault still remains in the right channel then you know the fault is in the amp.

This may sound a bit anal, well that's because the fault-finding process is anal

Good Luck Bill
