TTI Thurlby Thandar TSX3510 35v 10amp PSU

Have to say TTI have the best customer support and so cheap for spare parts.

Hmm... I have a handful of Thurlby PSUs here - mostly PL320s and a TS-something somewhere. I quite like them, although the earlier PL320s are a mess inside and not exactly easy to work on.

BUT, given that they wanted £35 for a service manual - which would have cost them nothing to email as a PDF - I can't agree with your comments about support. Perhaps they've improved since then (that was 3 or 4 years back).

They seem great to talk to over the phone for advice and also for parts, never asked for a schematic as the companies I worked for already had them from TTi, that's annoying about the schematic  I will ask them when I call next to see if they will email one or still charge!
Are you parting with any of your Thurlby gear, I have a bit of a fetish for it

I made this one following the LM317 typical application circuit. I added a small volt/amp panel meter to it, voltage adjust knob, and two banana jacks. On the back is a DC input from a 12v wall wart and power switch. I just ruined the display while I was trying to calibrate the volt meter.

I'm working on another one right now that has digital control and current limiting.

Nice COMPAQ screwdriver, bro.

It brings nostalgic moment, that thing was basically all over the place in 90s as promotional/advertisement item from almost major computer/electronic companies, you could spot at least one if you walked into a typical IT person's workspace/table.

These are the two power supplies i'm using at the moment.

I love how some manufacturers started putting "REMOVE PROTECTIVE FILM BEFORE USE" messages in huge font obscuring the view, so people dead-set on keeping their stuff "virgin" long past its warranty have no choice but to peel it off, already

Haha, each and every time i look at the screen, i'm tempted to peel it off.... it is not easy to control oneself from doing it.

Come on... you know you want it... and you deserved it... and it's Christmas, after all...

Just watch that protective film, I've had some films that bond to plastic over (a long) time making it an ugly mess when finally trying to remove it.

Just go and buy some cheap tablet screen protectors and cut into strips as a replacement. Easy on, easy off when needed and pretty invisible. Should be under $2 for most of the clone ones, and as a bonus they come with a cleaning cloth to remove dust and polish the screen before application.

Eew, that is a big pain if it happens.

Sounds neat, will give it a try. thanks.

I had a similar issue with some plastic bag I put over my Rigol 1052E to store it, it started to melt the knobs
You can't even trust Chinese bags anymore.

This is my favorite power supply. Built February 1958, 0-30V, 0-300mA and 0-25 ohm internal impedance. The most used one is a simple 5V power brick ...

Love vintage kit great to see it still in service. What concerns me though is the use of PCBs in capacitors and transformers in some vintage devices.

Capacitors, sure, but just because a transformer looks ... absolutely disgusting ... doesn't mean it's prone to failure.

He's saying PCBs used in the sealed transformers I think.

It's not really in service, I found it the other day in the attic at my parent's place. I do want to clean it up and carefully test it. Have to find a variac and a lightbulb first to prevent components from releasing the magic blue smokeir PCB's  when powering up.

Well it's favorite one... I've build it when I was 14yo... 15V/1,5A

It's unlikely that it contains PCBs in the caps or transformer. The caps should be DC electrolytics and they are PCB free.

My one and only "real" power supply, but it serves me very well.

[SeanB]

This is one I put together around 20 odd years ago to give me an AC supply from 0-12VAC at 5A. Isolated output, using an old variac. Originally the variac was designed for 115VAC 400Hz use, with a 5A rating, but on 50Hz 12V is about the maximum I will give it as a supply.

I have owned a pair of these Lambda LA-200 supplies for years.  I just picked up the Protek 303 at a hamfest on Saturday for $30.  It works well, but I would still like to have one dual-voltage supply.

It's probably not my *best* PSU, but it's my favourite and it gets used the most:
