Weir 4000 Bench Power supply circuit required. - UK Vintage Radio Repair and Restoration Discussion Forum

Vintage audio · 10th May 2023, 3:12 pm

Greetings to all.
I see in one of the closed threads that someone was recently able to supply a circuit for a weir 4000 bench power supply. I have exhausted all possibilities for downloads from all the usual internet sources so am hoping someone here once again may be able to help.
I am wondering if anyone might be kind enough to pass a copy on to me. I have a 4000 power supply that is constantly outputting 49 volts and is not adjustable. A circuit would be of great use for repair and calibration of this unit.
Many thanks and best wishes from south east London (UK)
John.

If this is the thread you're referring to I suggest contacting Julesomega directly by sending him a Private Message (PM).

Yes, thank you that was the post I found. I had previously tried to send him a personal message but as a new member I was not allowed to do so until I had made at least one post via the forums
Will do so now.
Many thanks
John.

A very big thank you to Julesomega who so very kindly sent me a copy of the full service manual. The manual I am sure will be a great help with my repair.
Thank you also to Station X who so very kindly corrected my posting error and gave valuable information.
Best wishes.

Just found a slightly sick one of these and was quite happy to find this thread, also as a new member I cannot message before posting but I will now,
Good luck to all in your repairs.

I find I can upload my Weir 4000 manual here as a PDF

That should probably be moved to the test gear section, as offered/wanted posts are now deleted 90 days after the last post. https://www.vintage-radio.net/forum/...d.php?t=194886

Indeed you are right David: my mistake when I was searching for a thread on the 4000. I'll have another go

I'll be wanting a Weir 4000 now and my Halifax says no!
