I too have access to a copy of that elsewhere database. I have "docfetcher" on my PC - it seems an excellent local search machine. It prebuilds its index, searches are almost instant, and also includes previews for matching finds.

The two 15v transformers all I can find is 0.75va and mine are 0.5va will this be OK?

0.75VA is a higher current rating than 0.5VA so would be fine as long as they physically fit, I'm not familiar with the Immersun so don't know how tight things are inside.

15v 0.5va tx:

If you do go for 0.75va, bear in mind that the 15v supplies are shunt regulated by a zenner diode, and rely on the high impedance of the small transformer to limit the current, so you would be wise to fit a bigger 15v zenner.

Thank you, that is some good advice..

I have managed to get the small circuit board off that holds the two transformers on.... OMG what a nightmare, they have put some form of silicone stuff between the two circuit boards. I cannot clan this stuff off without damaging the board, so my thoughts are just make a new one but because of this stuff I cannot see where the traces go, I cant even get to the pins...

Does anyone have a schematic for this or any idea where the traces go?


Many thanks

Soak in IPA and the conformal will go brittle and be able to be removed.

I love a good pint of IPA.

That did go through my head!!

Question about the two 15v transformers..

After alot of time I have cleaned off enough to see what was going where.., It seems that each transformer has two ouput coils but only uses one on each! could you not use one with twin coil ouputs and use both outputs.. just seems a waste or is there a reason for this??

Not isoprop fluid then?
