Default Connex Electronics TA2022Amp

Hi all,

First posting here, hope I won't bother you too long with stupid questions.

i just bought this stuff:


I hadd a hlly 90w amp, not bad... But the board blew up... So I intend to put my new pcb in Hlly case. So far, there shoud be no problem, except:

-can anybody confirm that the original hlly xformer will fit? it has one secondary (3 wires) 24-0-24 V and is rated 300VA.

Other question that tortures me a lot:

did anybody try to use these chips with balanced inputs?

Best regards

Sorry, but I don't have an answer for you on your questions.....

I am interested in your results though. Once you get up and running (hopefully quick!) I'd like to know what you think of the two amps. I'm interested in purchasing a 2022 amp but haven't made up my mind yet which one I'm going to get. I like the HLLY as I don't have an enclosure but the amp you just got could be a good choice as well.

I have the TA2022 amp module. THIS ONE

It is a solid amp for a good price. I am using a 2X22 200VA toroid for it as it does have on board rectification.
