Long shot circuit diagram request. Weston Electronics regulated power supply. Model PS-20

[John Crighton]

Hello All,
I picked up an old power supply at the Wyong field
day last Sunday. It is made by Weston Electronics.
Model PS-20 The rear label says 13.8V 18 Amps max.
I am guessing that the unit is 30 years old, maybe more.
Some of you enthusiasts may have a circuit diagram,
If so may I have a copy. I will pay for expenses.
There are a few components missing so the circuit
diagram would be nice to have.

Regards

Can't help with info sorry. But you weren't the guy who bought one for $20
when they wanted $50 were you ? If so that was a nice piece of haggling.
Cheers

I do haggle Jim, but that wasn't me. For this really ugly old power
supply, I only haggled from $20 to $10. All good fun on the day
and more fun getting it to work later, like now.

I walked away from a Philips 60 Mhz CRO with manual. It was a
storage type and dead. $30 asking price. I hummed and harred,
wondering about the tube then decided a minute later to go back
and take it. It was gone!
I am kicking myself now. Heh heh heh....

What goodies did you buy Jim?

John, I've been going to go to the Field day for 30 years. This year I got
there. That episode could fill a book, but I didn't see anything I wanted
badly enough to buy. I was too busy observing things, and finding out where
he heck everything was. (In other words the drive and sleep in the car
zonked me out ) I rekkon that a few signs would make all the difference,
after all a lot of people come a long way and may be first timers. Likewise
a few seats for the oldies (yes I found them eventually, lucky And a
person on the tannoy with a lighter attitude.
Boy for a first timer I sure am a whinger ) Full marks to those who
organised things , the above remarks excepted.
And full marks for the friendly people who went or manned the stalls.
Cheers
Jim
PS. I am now in demand up here, answering questions about what it was like
)

John,
I went to Wyong a couple of years ago and would like to go again if only
I knew when.

Where is it advertised so I can keep an eye out and go next time?

Might get some more nickel wire??

Hello John G,
here is the website.

A yearly event every February. I will remind for next year.

Keep an eye on this clubs coming events around June.

They usually have an auction of trash and treasure. The
man who is the auctioneer is a real comedian. I enjoy his
patter and comments. Meeting people, talking shop,
having a laugh and comming away with someone elses
junk is a good day out. I look forward to that one also.

Anyone know when the next trash and treasure is on
at the WIA , Wigram Street, Parramatta?
