Default Martin Logan Aerius i HT Board Transformer Kaputt !?

hi folks,

New to the forum from Scotland and looking for some of your expertise

I have a fault on my ML Aerius i's which I have narrowed down to the HT board.
Doing a bit of measurement I think I have an open circuit transformer on the board.

Problem is where can I get a new or equivalent one in UK/EU ?

The Part No is 60T2706 but I can't find any despite trawling google for hours.

Any help much appreciated !

Andersonix had an open secondary on one of the HV transformers for his SL3s.
He was able to get a replacement directly from Martin Logan for $16 + shipping.
I believe the transformer part number is the same as yours.
ML SL3 intermittent bias supply problem

As already suggested, your best bet is probably going to be contact ML support to see how cheaply they can ship you one.
Or, perhaps, they can put you in contact with a service center across that pond that could sell you one.

thanks for the info and suggestions.

Have contacted ML who have given me the UK agent details and they are the same supplier that quoted 300 for one HT board.
I have contacted them and hopefully they can supply the part rather than the whole board.

Will report back on progress.

Does antone know if there is any difference between Aerius & Aerius i HT boards?

The reason I ask is I have a couple of aerius ht boards if the OP gets stuck I may consider selling.

Alan Pm me if of interest and I can pull the speaker apart and take a picture of the board.

If ML in USA will let you buy one $16 transformer and ship to the UK (doubtful, because of their foreign dealership agreements), then you should buy two (at least). If the UK agent is too stubborn (or greedy) to sell you just the transformer, then I would suggest asking someone here in the US to relay an order for you. (I can't do it myself as I am going abroad soon.)

In the meantime, you can temporarily power both bias supplies from the same transformer with a long cable.

I am trying to source officially from ML right now, but if I need to maybe a kindly forum member could help - good call!

Looks like ML UK won't help at component level (but they will sell me the whole board at $480 !!)
ML USA can't supply to the UK due to international dealership rules etc so I need to find some kindly person in the US to order and ship to me !!

Unless of course there is an equivalent of the transformer that is more commonly available ?

Have you double-checked that the transformer is indeed the only problem by hooking up the output of the HV transformer from the other speaker supply as Andersonix suggested in post #6? If so, send me PM and I can handle the order/shipping for you.

We had no luck trying to find an equivalent transformer for Andersonix when his failed.
It's a pretty specialized part. Perhaps somebody with better Googling skills...
