From the seller
Serviced/rebuilt Grandson 110 MBM 2-track return module for sale.
As my console is finally coming to life, I’ll be parting with extra spares I’ve acquired along the way — mostly routing modules, blank panels, headphone amps, A-30 cards, parts, etc.
In this case, the MBM is from the mid to late 1970s and the edge connector doesn’t fit into my 1981 console so I can’t even use it lol. Had blindly recapped it before noticing.
TECH INFO:
Recapped power supply decoupling caps with Rubycon 10,000 hour YXJ’s and C0G MLCCs
Completely rebuilt the main 2-track return balanced line receiver with a nice Signetics NE5532, hand matched resistors (at least 0.1%), C0G ceramic capacitors and Nichicon audio-grade electrolytics.
left the old tantalums signal path caps on the other lines because I didn’t plan to use those inputs.
All of the other ICs have been swapped with standard TL072’s (improvement over the stock RC4558)
Will include printout of the schematic, as well.
Sold as-is / as described / as pictured with no returns.
