Having just retired I now have time to follow my past interests in the design and repair of audio equipment. Recently I have been asked to look at two Techron 7560 power amplifiers (sometimes referred to as power supply amplifiers), these are I understand equivalent to Crown M600 units. Their specifications are impressive, even by today’s standards. I have completed a couple of minor repairs and I have performed some basic tests to prove the frequency response, noise, output power and distortion (towards to onset of clipping I managed to get 1,500W into 4 Ohms (1kHz) at c.0.1% THD).
These units are switchable for a.c. / d.c. input coupling and are probably well suited for sub-woofer applications. However, they are large (6U), heavy 41.7Kg (92Lbs) and have two permanently on cooling fans. The owner wants to sell them and has asked, given their specifications, if they are something of interest to the audio community. I would therefore appreciate any views from the DIY Audio community as to whether these units are of any interest to community members. If so, and if my understanding of this forum works, I will arrange for the two items to be posted under the Market Place / Members Market area of the forum. This is my first post under the forum and apologies if I have misunderstood anything.
Your feedback would be welcome.

Hi 2tank
Many thanks for your interest.
The units are back with the owner and are now on Ebay:
https://www.ebay.co.uk/itm/18549936...WwgExNA5O+5/tOEuqKxW9Pv+F11S|tkp:BFBMqNTDiuxg
I assume that you are currently located in the USA and therefore these units may not be listed on Ebay in the USA as the packing and shipping costs are likely to be high (92 Lbs. each)
You could make an enquiry through Ebay to the seller if you are interested.
Regards
Jon
