Hello

In my continuing search for rare components, I'm looking for the following -
can anyone help please?

MFC6070 - a Motorola 6 pin "quip" packaged i.c. which is a 1W audio amp
(1970s/80s discontinued)

TAB101 - a variously-manufactured germanium transistor ring modulator in a
TO-74 or TO-100-10 metal can (TO-5 with ten legs), also 1970s/80s and now
discontinued

(See below for more info)

I haven't found any online suppliers, not even via chip brokers. I know I
can build replicas from other chips but I'd like to source some drop-in
replacements for some restoration work I'm doing on these EMS synthi AKS
music synthesisers I have been given. Can anyone help me to find some of
these please?

Cheers

Can you cross this into any ECG or NTE type numbers? Or, others like RCA .
???
I have many old solid state components in stock.

I can't find any information on alternative part numbers - I do know that
Mullard made the TAB101 and it was around in 1969 and later.

I haven't (yet) identified an MFC6070 cross-reference or other Ge ring mods
that might do the job. It was a good suggestion of yours, so I shall keep
looking and report back.

Thanks
