I'm the original owner of the one of the TFM-35X and A-760x. The other TFM-35(X)s have been nursed back to health except of the one X that started on fire - it's almost back except for a DC offset on the output. That unit has been through a lightning strike and repair but other issues soon surfaced and hence the fire lol. Currently, have the M1.5T showing life (after a butcher job) but it's in ICU - getting some output but one channel is really limited. I'm looking for some help in finding how to perform the bulletin upgrade for the "speaker thump". Any help would be greatly appreciated. Thanks!!
