That's a pretty good idea. I haven't asked Jon if he could give me instructions, because I know he does this for a living. Offering him a consultation fee would make me feel better and hopefully make it worth his time. I know I would get more satisfaction if I could do it myself. I'll drop him a line. No harm in "fishing around" for others' experience, though. Anyone out there made this conversion before? Thanks.
How to convert Class A/B amp to pure Class A
Hi. I own a wonderful Threshold Forte Model 3 solid-state amp. It is a Class A/B design that is rated at 200 wpc into 8 ohms. I have read that it is essentially the same amp as the Model 1A, which is a pure Class A amp rated @ 50 wpc, and that it is fairly easy to convert the 3A to the pure class A configuration (and consequently drop the power output to 50 wpc). I am fairly handy; anyone have any suggestions? I have read that constructing a brass or copper rectangular plate to connect the inner-most screw lugs of the 4 big caps is a good start. Any suggestions? Many thanks.
