Hi Aryeh,
I once used a transformer that comes with PZO microscopes (Polish Optical
Company). You may try to google for "ZM6/50 PZO", it's the one with a
sliding pot regulating the output to 0 to 7V. But it may be hard to find in
Israel...


You may also try to tweak some switching mode power supply, preferably a
laptop one.

Or you may try one of these cheap ones:

http://www.ebay.com/itm/DC-to-DC-Step-Down-BUCK-Converter-Adjust-Constantt-
Current-Volt-Max-5A-TW/131299324389


and power it from other supply (12V or 24V). Both voltage and current limit
are adjusted with 10k pots, so it should be easy soldering... (I also
recommend using some other load than your precious 6V bulb for testing!).

Also a regular lab power supply would be a solution (alhough expensive and
bulky, moreover they seldom supply 5 Amps).

Good luck, zdenek

Not confocal, but I hope within the list's expertise.

I have an Accuscope 3032 microscope whose halogen lamp PS is dead.
It appears to be a 6V DC 5A (max) supply whose output can be adjusted
with a 10K pot.
It lives in a box (roughly 10cm x 6cm x 2.5cm) which is labeled
Model No.: YX010~50-30-01
and calls itself a
SWITCHING POWER SUPPLY TRANSFORMER.

No company name, and my internet search turned up nothing.
Of course I wrote to Accuscope -- no reply.

I can use an adjustable linear supply, but that is big and heavy.

Does anyone on list know where I can find this?

Thanks in advance
