FYI: New TTi Power supplies

[kxenos]

I recently came across this item on ebay and I bought one:
http://www.ebay.com/itm/Thurlby-Thandar-QL355-Precision-Linear-Power-Supply-35V-3A-15V-5A-/281011316510?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item416d94671e
As the price was almost half of the one found on Farnell (330€ with shipping vs 550€ plus shipping) I wasn't very sure but I gave it a shoot. The delivery time was 4 days and the PS is genuine TTi and working great.
I'm not affiliated with the seller in any way other than being a customer.

I wish we could get these in the US.

That's a beautiful unit, and I'm glad TTi can still thrive/survive making units in the UK.  Prior discussion with photos.

For USA buyers, a unique design and peerless stability to 1uV, see the Power Designs Precision Power Supply thread.  Its not digitally programmable, but its sold typically for far under $100, depending on the amperage.  Its peerless because modern voltage sources that meet or match the PD capability will cost >>10x more.  They were built and designed over 40 years ago, and still working to spec, unrepaired, and built like tanks.  I have 3, others have more.  There are interesting photos on Flickr by PD fans.
