Default Re: Hi From Cathy Lissen/Eveready Kenilworth??

Attached is the current universal transformer sold by RS. The terminal annotations are the same but not necessarily correct for your transformer but a good bet that they are. For an 8k Load for the A70D into a 3 Ohm speaker suggests using tags 1 and 3 for the primary and tags D and C for the speaker.

Looking at the circuit, I suggest you change all capacitors that see the HT, the three I have in mind are C12, C27 (both 100nF 400V) and C34 2.2uF 450V.
This assumes you have already replaced the MUST DO THAT capacitor C35 47nF 400V.

The Mica capacitors will probably be OK so don't change them just yet as alignment may be upset.

Good Luck with this one, it looks a great set to recon.
