Default Re: Re Marconi 2022 2955 OM345 OM360 Replacement

Hi John,
this is certainly a perennial problem with the Marconi equipment of this era. I have replaced quite a few myself, with original NOS OM-345, mainly in 2022-series sig-gens.

Distel used to stock OM-345s but are now sold out.

The Marconi forum on Yahoo has had a lot of discussion about possible replacements using MMICs. I don'y know if you have checked the posts there out.
This included one supposedly fully-tested module from a chap signing himself "Steve in Cornwall" for about £10. But he does not seem to answer emails or posts on the subject now.

There is definitely a demand, if they can be made at a reasonable price.

I will PM you my email so you can send me details off this forum.

By the way, if you do offer modules via this forum, make sure you use the For Sale section and give an exact price. Sales via this forum are strictly regulated, to protect forum members

Good luck - these replacements are definitely needed!

All the best

Jeremy
