ARC52

did you ring the number i gave you, i’ve also got a contact for a shell i beleive it was being sold at newark on behalf of the britannia retoration group

Thanks Twin Pin

we have a couple of non functioning sets all we’d what is a donation to the sea vixen restoration fund

Guys without hijacking the thread i am looking for this particular set for my cockpit project.Non functioning display only.Any leads appreciated 🙂
Thanks Twin Pin

essentially that is what we’re doing too, piggybacking a modern tranceiver (not sure which one) onto the existing wiring to make use of the link throught to the ejector seats via their respective PEC’s (as we’ve got a few PEC we can modify) there should be no need to use long leads or external intercom connections as we will be on air, the headset’s will be modified via adapters to work with handheld tranceivers as our PELTOR headsets are already designed for use in noisy enviroments ie noise suppressed, our guy from loughborough has it all worked out in theory at least, should make ground operations the safest they can be especially with the limited visability available from a sea vixen during functionals

Tom,
the amps are “plug compatible”, i.e. there should be no difference in the operation, I/O etc, it’s just the “guts” that are different. We have had poor external comms on the Sea Vixen and have swapped the amp a couple of times, both types have been fitted without a problem. (Our problem lies in the external JB’s or connections).
We are in the early stages of a re-design using modern IC components, hope to have a prototype operational over winter. We can then look to having a pcb made. We have a number of aircraft that use this amp and only a couple serviceable. Re-designing it will give us “unlimited” spares.

i think tom wants a working transceiver in the hunter too

Would you happen to know if the Hunter uses a valve type amp. or is it the transistors?

And are they type particular, for example if you put a transistor type into an older aircraft, would it work?

Thanks,

Tom

When our man returns from the US I’ll get the manuals/diags copied for you. Not sure when he’s back and when I’ll get the manuals; so it might be weeks rather than days unfortunately.

The ones we have are of the older type with the valves and rotary transformer, and that is essentially what we are doing replacing older components for modern equivalents great minds think alike

whenever you can get us a copy we’ll appreciate it

There are at least two versions of the 1961. Happily the two major variants are “plug compatible”. The older version is a valve unit and has a rotary converter and is easily identified by the noise it makes. The later version is quiet and uses a pcb with transistors.

We have both diagrams and manuals, unfortunately the man who has them is in the US with the Lightning; he’s due back shortly.

We are also contemplating re-engineering them with modern components and a higher output drive. Still in the planning stage but there are quite a few of these amps still in use and not many spares.

just to add to matts request has anyone got details of the A1961 amplifier unit fitted to the vixen and many other aircraft types.pin outs of the connections and internal circuit diagrams if poss.cheers in advance chrisw.

cheers mate it’s for the guy at loughborough that is a billy whizz on comms i’ll discuss what he’s planning but it’s quite exciting considering we now have a working VHF radio system in the vixen

Matt,

The ARC52 is also fitted to the Bucc and my manuals should cover what you are after. I will have a look later and email you the drawings.

Cheers,
