This was buzzing through the speakers. One of the 2SD130 transistors had expired. I replaced both with BD130Y as they were hanging around at the time. I also replaced some of the capacitors on the power amp board. This was an old amp from Dixon's in the early 70s, I know, I had one; bought on HP, £49.99! should have known better, sold it and bought a Rotel RA-610.
