I would check all the R33 wirewound resistors as the have tendancy to fail
Yes. Thanks, I will get some new components today but not the 330pf. Must order again. Some components have the wrong value on board. so I will try follow it around and check. Where do you find the R33 wirewound resistors?
Farnell have a good range but if you don't have an account you may prefer Amazon who seem to have lots.
These would do, they have some that would be a better choice but not on Prime.

These are 2W and quite small.
If you plan to drive 4R loads for long periods then you could use 4 in place of each original resistor (2 parallel pairs in series).
I didn't like the look of the 3W carbon film ones at Amazon but the 5W "cement" ones would be OK if you don't mind waiting.

There's a row of 3 r33 wirewound resistors down each side next to the power transistors. I bought some off eBay
