The ones I rebuilt were the FTX2001 Series 3's. There were two which im now using as mono's (bridged) however since then I have found and purchased Ashly's highest power amp they made (at that time) which is the one im working on now. the Ashly MFA8000 and yeah apparently the MFA name is very apt for this product.

knight2001dts Posted February 15, 2020 Share Posted February 15, 2020 (edited) Finally - the rebuild begins - on the no doubt still untested amp? This thing is pure awesome - can't wait to see what it can deliver to the *untech's (tm) hahaha (the above needs an Evil "C" dropped in there ) Edited February 19, 2020 by knight2001dts Link to comment Share on other sites More sharing options...
tubularbells Posted February 18, 2020 Author Share Posted February 18, 2020 I was always taught to play with my food and have found it also to be true with speakers. Keep on moving them around if you ever get sick of/tired of the sound. You never know if theirs a better sounding position unless you try....right? 3 Link to comment Share on other sites More sharing options...

tubularbells Posted February 19, 2020 Author Share Posted February 19, 2020 (edited) Just performed the voltage conversion on my MFA800 amp to see if it works before I begin the referb and am happy to say yes it does work and is a sledgehammer in terms of power compared to my FTX2001! One potential issue though is the RHS transformer hums louder than a swarm of bees so need to find a way at reducing that (any ideas welcomed) Edited February 19, 2020 by Tubularbells Link to comment Share on other sites More sharing options...
frednork Posted February 19, 2020 Share Posted February 19, 2020 remount tranny with (sorbothane?) footers or dc blocker or both. Has worked for me in the past 1 Link to comment Share on other sites More sharing options...
zero1 Posted February 19, 2020 Share Posted February 19, 2020 I've a DC blocker you can borrow to try, or there's my power regen also sitting idle with my system currently out of action. Does the MFA8000 have a captive power lead or IEC socket? 2 Link to comment Share on other sites More sharing options...
tubularbells Posted February 19, 2020 Author Share Posted February 19, 2020 Thanks gents as the hum is only occurring on one of the two trannies I suspect this is not DC related. Interestingly (or maybe not so much) is is coming from the side which was clearly dropped as it has a bent face plate so suspect it may have delaminated. The amp comes with a captive cord so I need to swap out the plug at some point. 1 Link to comment Share on other sites More sharing options...

tubularbells Posted February 21, 2020 Author Share Posted February 21, 2020 So after a few days of listening ive reluctantly concluded the speakers will remain in this position. I say reluctantly not due to the sound as like i mentioned earlier it just seems to give me more of everything but instead it does make the room look pretty crap with the speakers sitting nearly in the middle of the room as well as being offset but the upside is that they are both well away from any hard reflective surfaces which is probably why im getting better sound. Also trying out some new speaker cables courtesy of a very generous SNA member. 5 Link to comment Share on other sites More sharing options...

No visable markings on the cable and appears to have been re-terminated at some point as its got different sets of bananas on each end. Beautifully made though. 1 Link to comment Share on other sites More sharing options...
russell66 Posted February 25, 2020 Share Posted February 25, 2020 Inspired by your video and post I got my TOA amplifiers out. They have Hot Cold And Earth screw connectors. I altered an RCA to go hot and cold and then ran an earth wire somewhere. They sound pretty good, lots of power and space, maybe a little harsh but I haven't played around with it much. Not too sure what I,m doing but I was wondering if you have any advice or if this is something worth pursuing. Thanks Link to comment Share on other sites More sharing options...

Maybe this approach was done back in the day to reduce ESR but all I know is it s a lot of caps to de-solder and re-solder being particularly difficult due to being a multilayered board (any tech would understand my grief here).
