Follow-up: Vendor now on eBay for Fairchild 75325DC in lots-of-five; they accepted my Best Offer.
https://www.ebay.com/itm/333675901157 So now I can get back to making some progress on repairing the H222A in my MM11-DP :-}! From: pbir...@gmail.com Sent: Friday, March 11, 2022 10:01 AM To: General Discussion: On-Topic Posts <cct...@classiccmp.org> Subject: Seeking a MC75325L Dual Memory Driver I have here in my hands a DEC H222A (16Kx18), part of a MM11-DP, that took a blow at sometime in the past. In consequence there are a number of small parts damaged (snapped diode, crushed axial electrolytic, chipped mica capacitor, cracked/broken SIP resister net) but those all appear to be relatively easy to replace. What's not so easy to replace is the MC75325L Dual Memory Driver (L = Ceramic) that was de-lidded in the process :-<. I am wondering whether anyone has one of these ICs in their spare parts drawer that I could acquire? I do see a MC75325P (plastic) on eBay at littlediode_components for ~20USD, plus a surprisingly modest shipping charge (Royal Mail International). UTSOURCE claims to have a supplier of the ceramic part "new", with a significantly higher shipping charge. Before I go with the ceramic part (IMO not the sort of packaging that gets . remarked) I thought that I would check here for alternative sources. Thank you, paul
