Jeff F 13 Posted October 17, 2023 Share Posted October 17, 2023 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!!

Many models this is 470uF, but others have 220uF. 22 hours ago, Jeff F said: I'm looking for some help in finding how to perform the bulletin upgrade for the "speaker thump". For which model? The m1.5t does not have a thump fix bulletin. It's one of only a few models (m400 series) that does not have a power switch. It's "instant on" as soon as it's plugged in. 2 Link to comment Share on other sites More sharing options...
radtraveller 213 Posted October 19, 2023 Share Posted October 19, 2023 Put in a dedicated 20 amp circuit (or 3-4) in with their own nice wall switch… 2 amplifiers per circuit. ?? Dang.. would need a new panel… Never mind….. 1 Link to comment Share on other sites More sharing options...

Jeff F 13 Posted October 20, 2023 Author Share Posted October 20, 2023 Thanks for the tip on the DC offset and the info on the M1.5T bulletin (that doesn't exist). No wonders I could not find it ... lol. Read somewhere that there was ... now I know ! Jeff 2 Link to comment Share on other sites More sharing options...
