Hi,

I posted a message a little while ago regarding a JVC VCR which had
popped some of the PSU parts during a power surge. I managed to track
down a couple of transistors which had blown and I've replaced those
but it seems now there's no voltage coming out of the transformer (ref
des T5001) but there is going in so I'm of the opinion the transformer
has melted inside.

I'm having trouble finding this part in Google though. The writing on
the part is Delta 41H-2001 0186-1 DCGM 0306B.

Does anyone know where to find a spec for this part and/or some place
that sells them?

Many thanks!

Sorry, forgot to mention it's a JVC HR-S6965 VCR.

As a last resort, take the transformer apart and look for a Fuse or
Thermal Link.

look at what V reg(s) and fuse(s) it feeds.

Ah! And history repeats itself ... d;~)

Even assuming that this is a conventional transformer in a conventional
linear supply, it is likely to have several windings for custom purposes
such as powering the VFD filament, and will not be replaceable by any 'off
the shelf' type. It might be helpful if the OP said the model number rather
than just the make. If it's more than a couple of years old, it's likely
anyway that his local friendly repair shop will have a pile of them out the
back that he can rob a tranny from.

If it's a switch mode power supply, and it almost certainly is, then I would
venture that your problem is elsewhere. Bad caps, shorted diode, bad
optocoupler, etc.

Yes, quite. 1980s stuff may be single winding - but either way if the
OP looks at what its feeding they'll find out one way or t'other.
