Hi!

I am picking a Crown Xls 202 apart, just for the fun of it. Have had it for sale for a year but no one wants it for 100e..

Well, the transformer has these markings on it:

toroid international LTD
P/N: TI-64851G
Harman: GB202

strange number aside from the other:E115159

SL 0142


This si the strange markings i find on the toroid.. The company name, i couldnt even find a working homepage for them.. so.

I would like to know the output of it and the VA it produce.

I hope it will be in the area somewhere 50-65 V + - and hopefully around 500+ VA.
do someone know anything about it? It wights circa 4-5,5 kg i believe


And the transistors in the amp, the output devices: MJ15024/MJ15025,
are they something that is usefull?´

I a only interested in high power amps, 200w is minimum for me. The Leach amp is another story, even if it doesnt have the power i want, i am still going to build it to mymothers home stereo probably, or use it in the kithen.

thanks in fore hand

Crown rated that amp at 200 Watts into 8 Ohms and 300 Watts into 4 Ohms. 200 Watts into 8 Ohms usually takes about 80 Volt rails. You can to the Crown website and look under "discontinued amplifier products" and all sorts of info there.

Crown XLS 202 was originally the C Audio GB202, which was rated at 145W/8R, 200W/4R, 250W/2R. Power rails probably +/-60Vdc or so, with extra tappings to supply +/-24vdc for powering relays protection etc.
The transformer is probably about 250VA and was custom made by Toroid International who now go under the name of Noratel.

MJ15024/MJ15025 : Very nice if you want to make a 200-600W amplifier.
Watch out for those live heatsinks though.
