Yes - that's about right. I've seen Inkel stuff here go for silly prices. They do have a good reputation among the local hifi buffs.   Smile

The most powerful transistors on Yugo-communist-disaster market was a dodgy 2N3773 and manufactured by EI Nish. Motorola MJ15003/MJ15004 were in my wet dreams. Thank God those days are history. LOL  



There not fake mate,this are proper MJ15003,i wish i could find more of these...trust me i tryed to kill a pair of those in heavy load with no succes :) so i trust these Motorola MJ15003 with all my heart,on top of that Cloud fitted these outputs on there PA stuff.

Here we have Vermona Regent 2023 with Tesla KD503 on outputs 2 each ch for i think 100w rms/ch these ,,things'' are loud as hell....as a fault the vu-meters didn't work (some ground wire was reduced to ash somehow) now is fully working with all the parts original from...1980 maybe?!? i did resoldered all the driver boards and changed the thermal paste on the KD503-s just to avoid further problems.Btw....it has dc speaker protection with relays on both ch :D

Soundcraft Powerstation 600 i currently own 2 of these and one 1200,this one in the photos was loosing power at high volumes in 4R loads,so the main supply capacitors 6 of them needed to be replaced so i fitted 6x10.000uf/80v samwha capacitos,increasing a lot the power reserve with no side effects as the rectifier bridge can take the inrush current at start up,now the mixer is acting perfect with a lot of power reserve if needed Wink

^These have cropped up before. TSR was something to do with Bass-Charrington/ Tobysound, they were installed in almost every pub in the UK in the late 80's. From memory, it even has a mic pre-amp in there too, for pub PA.
Be seeing you.

Citronic Conquest C12 (V12) same amps by all means,this one faulty on ch1,2 blown BUZ outputs and shorted BTA12 (the 12amps  triac from crowbar protection),remember that these series have smd driver boards that tends to suicide and almost impossibile to repair Cry also the output devices are a mix of single and dual die lateral mosfets...not something i like to much....
