Thanks, but just to confirm, it's the power transformer, not the output transformer I was referring to. , although I do realise it may be a replacement, but def a proper, potted, B15 replacement, if so. I'll check out Psionic Audio JIC.

Hoping I can get some info on my B15 mains transformer. Connections all seem correct, and agree with circuit diag under amp. Tube rectified, non-pcb version. Amp is run from a step down transformer, and is working fine,( just need to lower the hum level a tad ) However, there appears to be two additional leads attached to the transformer , blue and blue/white , taped off, and tucked away. Can anyone throw light on why they are there ? I don't want to guess ! Thanks, Mike.

My Sonic Blue Jazz Bass , close replica of the Jazz bass I played in the late '60s, headstock and all , but mine had dots, not blocks !

Hi Rob, Real,Real Long shot, but do you still have the Green glow in the dark filament ? Thanks Mike.

Was great to meet up with Chris last week, when he picked up an amp and some "black boxes " ( my wife's description ! ) from me. Had an enjoyable chat 'bout bass things , even though we were pushed for time . Chris was well organised, and a pleasure to deal with ,communicating well at all times , despite some "logistics" problems which Chris quickly dealt with. Basschat at it's Best ! Thanks Chris, Enjoy the amp.

Hiya, Try Demeter Windings, Chelmsford CM2 9TE UK Company, They made me a new transformer for my Trace Elliot V6 Good Luck, Mike.

Hi Rob, I did contact Westside, but received a curt reply that Mesa service is now down to Gibson ! Not entirely unreasonable, I suppose, as there have been big changes at MESA, who have been very helpful. However, as you know, I'm a semi retired engineer, metalwork ( bent facia panel ) no problem for me, and I'm making a jig so that the replacement pot is accurately located on the pcb . Looks like the master volume pot is 100k ohms , log , taper a bit harder to identify, but 'bout 25 % . Just gotta find the correct 16mm pot , and I'll hopefully be sorted . Will get my tech to fit pot , I'm fine with the old leaded solder on my old valve amps , D-800 probably uses lead free ! Using my ( over 40 years old ) A.M.P. BH-420 in the meanwhile. Lovin' it ! Best Wishes, Mike.

Unbelievable ! What can I say ? "above and beyond the call of duty " comes to mind. Thank you so much for your positive reply . It's a great relief to know that there are repair possibilities for my Mesa D-800, despite living in the UK. I did, in fact, knock my amp off the speaker the previous week , in its carry bag, but thought no more of it ! Again, Thank you, I will message you, as suggested. Best Wishes, and Seasons Greetings, Mike

Can anyone shed light (sorry ) on my Mesa d-800 limit light being permanently on ? Amps been fine , 'till suddenly, when I switched on last week , no instrument attached, the limit light came on, amp hums, and controls seem all over the place ! what to do ?

Can't thank Dave enough ! Despite living at the other end of the universe (OK , UK, ) he happily agreed to to drive the odd 240 miles or so, and meet me at a Sheffield service Station to collect his Acoustic Control corp , and Ampeg cabinets. On the way down, He also collected a couple of 60's Vox AC30 stands for me , in Sunderland. Despite both our drives being in the 4 to 5 hour time scale, We arrived within 10 mins of one another. Then the fun started . First cab wouldn't go in the car. To my amazement, Dave started pulling bits off his car, and finally, with a big push , it popped in ! Gotta hand it to him, he's not easily deterred . Good thing, could have given us a big problem. Everything else went in, Just, then quick chat, and we were off. Shame we didn't have more time, but Dave had to be back, and I had to go to Birmingham on the way home , and escape before the rush hour . All in all, Dave's organisational skills made everything possible, and , just like the last time I met him , a pleasure, too. Thanks Dave !
