workshop cleanout | For Sale | Forum

I'm cleaning out my workshop and want rid of some of the accuulated radio parts. Too good to skip, but someone might want some of this.

Here's a photographic  sample…

A few valves, and some bases…

Several circuit boards, mostly for VHF repeaters

A VHF filter, one of several

resistors

Transformers galore

A big crate of meters

Doorknob and other HV caps

Variable airspaced caps

All sorts of heavy resistors

Toroids galore

Ceramic insulators

Relays including some coaxial

Potentiometers

Various heat sinks

Some heatsinks have a VHF PA attached.

Vacuum variable cap

Toroids and ferrites by the box

Some unusual items sich as this recitfier

and loads more like this…

and this

If you're interested, get in contact, either email or phone.

There's other stuff not pictured, including a triband HF yagi, various other antenna parts, an HV PSU for a big amp (4kV, 1.5A), complete and on castors as its so heavy!, and two chassis of linears, that could be re-built. (6m)

Some of this I'd like a few pounds for, but most if free for the taking.

edit.

I can't easily line up the text and images. But if you don't recognise the parts, you don't need them anyway!

Yes I'm a horader, that's why I have so much junk (well good stuff!).

But the shed is supposed to be a 2 car garage, there was only ever room for one car and my junk, now the other car is out to do any work in there…

I've stripped a pile of old radio chassis I had, saving the good bits, and scrapping the metalwork. That filled my trailer!

The coax relays could be used at either VHF or HF, but they're not high power. Would handle 100W, but not for downstream of a linear!

In the pic, the two at bottom left are direct wired with coax.

The two bottom right, one black with TNC connectors (I think they are), and bloe one above that black one is mounted on PCB and coax solders to connection points that way.

Could make a low power masthead preamp?

I have some more, but used them in a high power handling 6m masthead preamp, which I have yet to use in anger, but have tested. That with a sequencer and all.

Does no-one construct anything these days??

Why not use the sequencer that comes with it. (you read too quickly?)

Has little green flashy leds on front of a nice aluminium box with another winky to show it's "heartbeat".

The box with preamp has heavy relays that will switch medium current, but sequencer means that its not really "hot switching" anyway.

The preamp board is the kit that Colin was selling some time back. Seems to me a good design.

HNY to all, from "sunny" Blackburn!

I've put some pictures of the various stuff that I have for sale (or free to the needy), here…

You should find some brief description with each image (except the out of focus ones!)

Get in contact soon if you're interested in any of this. Some moved yesterday, and others are interested.

I'm guessing that you'll need about 28-30V transformer to do a 24V DC PSU after regulation, a bridge recitifier, some 2N3055 transistors, perhaps 2-3, a voltage regulator and  some smoothing capacitance, say 22000uF@50V and a few other minor components, connectors etc and a chassis.

Think I could do all this except the chassis. Main item is the transformer. I'll have a look on Saturday at whats there. Might have to connect a few up and see what comes out the other end?

I'll let you know.

I had a good look and guess what? I found a complete 24V PSU 

It's about 280 x 130 x 120mm. Maker Farnell Instruments Ltd Wetherby, Yorks. Model F24/5, stabilised PSU. Serial 000671.

5A fused output, Connectors are a sheilded row of spade type ro screw terminals. Quite a neat unit, a bit heavy, but should do your job.

Next thing is how to get it to you? Want to email me to set that up? I'm in Dunfermline Tuesday – any good? You make a donation to the club funds and its yours.
