Got home from Christmas vacation to some presents.
My globe Marconi MH4 arrived, except they aren't Marconi MH4. Billington got it wrong, they are Mazda VR37, an alternative construction Mazda AC/HL. That's okay though, this is another rare one that I didn't have in my collection, the price was fair.
Love those big plates. One of the four had a partially broken heater pin, which was a little disappointing, but nothing a little solder couldn't fix.
Listening now, they sound great, very linear, spacious. 90-year-old tubes.
More HY69 arrived. Will just show one pair, but now have around forty of these tubes. I put together a triode LTSpice model for these including A2 curves, so I have a few schematics I'm playing with. Long term goal is a lifetime supply for a special speaker amplifier. I have a special one already, so just going to hold onto these and scheme...
While I am figuring out the metal grill situation for the Forte IV, the plan for the Snells is to order another VIFA woofer to replace the one that was punctured. Once that's fixed, going to bring them to a local shop that does consignment of vintage hifi gear. Will package them together with the Sound Anchors stands. Not sure how much I will ask for them yet, but it will be a good find for someone, price will be reasonable given what the custom stands cost, not to mention the souped-up crossovers and brand new drivers. If nothing else, putting them on sale will get them out of the house to make room for the Fortes
looking forward to getting those into my system, they will sing with these flea-watt amps.
