Hi Guys,
Further to my request for info on the changeover relay used on this Amp.
I located one at RF Parts.
Not the same number but much the same specs.
ie. 3PDT,5amp contacts. It is also a Potter and Brumfield make. P/N 2235.
$25 from RF Parts. (excellent delivery to Ireland.
Why Heathkit used a 3 Pole relay I don't know as only 2 Poles are used.
RF Parts list a 2PDT also which I reckon will work.
 Both relays appear to be physically the same size and mount in the same
way. Just have to remove the securing screw from the relay, comes out
easily with a pair of pliers
I fitted the one I bought from them and it seems to work.
Amp is now producing the Watts.
Just for info, Hope it helps somebody else.
