Polyprojectitus has run rife, and I've got to get my workshop stock down. I'm only likely to use 2% of this stuff in the next decade, I'm not sure I can afford the space (shelf-space or head-space) to keep it all. So a lot of it has got to go.
Most things are yours for the cost of postage and a donation to 4HV. I am happy to post anything anywhere, but some of this stuff is pretty heavy and might be better mailed domestically (UK) or even to callers (St Albans). Most things are second hand, rescues, pulls, but they all work. Some things are new. There's probably no practical way to catalogue everything that could go. I'll list the most significant or numerous items, but it's worth dropping me a PM if there's anything you want that the list below suggests I might have. I may have it, I will almost certainly let it go to an enthusiastic new owner. Most things I have data on or can measure, and can provide some sort of assurance that they work. Pictures on request. I'll be trickling the new and shippable stuff onto fleaBay over time when I get round to it. Don't make me go to the tip with it. I do travel the country from time to time, visiting relatives and dropping offspring off at university, so might be able to deliver things.
TC secondary, about 1000t of 0.6mm wire, 110mm diameter, unused SRSG disc, aluminium, insulated from 1/2" bore (intended for bench grinder spindle)
2 off 1kVA transformers - 2x110/115/120v pri, 2x24v sec A whole bunch of other transformers lots of 240v fluorescent tube chokes of various sizes (for TC primary ballast or DCTC charging inductors) toroidal transformer cores 2A 240v variacs instrument cases - a few new, some with PSUs, more or less intact front panels Alli boxes 2 off "heatsink cases", used to house Metcal RF soldering iron power supplies (make a good free-standing audio amp box perhaps, that's what I rescued them for) A lot more heatsinks in the 10+ watt range
Lots of insulated heavy stranded wire (2.5mm2 IIRC) in odd colours (purple, pink etc)
ferrite transformer cores, some wound lots of FX2242 cup pairs with bobbin, inductance and loss data to 10MHz
lots of 63v electrolytics - 10,000 and 15,000uF, quite a few at other voltages capacitors - power factor correction / motor run, MOC, photoflash capacitors - tants, plastic switches
