Hello. My name is Phil, I own a pair of Antique Sound Labs AQ-1006 DT (845) Monoblock amps. These units are about 25 years old and have served me quite well during that time. I like them so much that about 2 years ago I had them refurbished and swapped out the stock Power Capacitors and just general clean-up and maintenance to prolong the life of the amps for as long as possible. Recently one of the amps failed and no longer puts out any sound to the speakers. It powers up just fine, and from what I can see the digital bias meter and tubes all light up. In the course the warm-up I hear a very loud "POP" through the speaker and then a very loud and noticeable "HUM" while the system is in standby. Not the normal hum you will get from tube gear but a very loud hum that can be heard from more than 10 feet away. I surmise that the pop and hum were the preamble to the amp now not playing. Based on what little I know about the amps my guess is that I have lost a Power Supply, but I could be wrong. Whatever it is I believe (or rather hope) it is a straightforward fix to the problem, but was hoping to find someone that would be able to properly diagnose and fix the problem for me. Is there anyone in the community who is able/willing to work on it for me?. Or direct me to someone who can. Any suggestions or information is greatly appreciated. Thanks in advance. BTW, I currently reside in Central Texas but I am also willing and able to ship the Amps outside of my home state for repair services if necessary.

Apologies. I reside in Central Texas, but I am not limited to finding someone local who can assist me. I am willing and able to ship my equipment outside of the state if necessary

@euro21 thank you very much for the schematic and also for the TonyTecson contact. I initially saw his posts on the forum which is what sparked my interest to join. I was hoping to get in touch with him directly, but could not figure out how to do so especially since the forum was closed for replies or comments. I was trying to determine if he resided in the CONUS or OCONUS. I wasn't sure if there was a way to look him up via the Members portal. I am still trying to learn how to navigate the community. Thank you again for the schematic. Much appreciated.
