Hi Bill,
Gosh, we haven’t exchanged e-mails for—literally–-years now…! You may recall me from those heady days of yore when we both worked on / built / modified / boast of our respective MFTMM receivers…
A good friend of mine—Bill, VE3CSK—is in the process of collecting parts for an HB receiver, & I’ve been trying to sell him on the idea of an MFTMM: I keep telling him it’s an excellent “foundation” receiver, & that it’ll prove to be much more than a toy, or pleasant diversion, if he leaves enough room on the chassis & the front panel for future mods. I think I may be finally winning him over: he’s asked me for the references to the rig, & has placed an order for a National-brand slide rule dial with a fellow Stateside!
Do you still have your receiver, Bill…? If so, do you have any nuggets of info that might be worth sharing re. it, that I could pass onto Bill…?
I’ve since built yet another superhet here—in keeping with my interest in 1929-ish radios, I built this thing, & have been having a ball ever since: http://www.superhets.info/page9.html
This rascal can REALLY play—but it’s a LOT larger than my MFTMM rig!

Hello Eddy! Great to hear from you. I like you FB page on the Super Hets. Beautiful.
Yes, I still have my MMRX. Haven’t used it for a while, but I am thinking of putting it back in operation — I am now getting active on 75 and 40 AM, and it would be fun to use this RX.
Here is an idea: The 455 kc filter crystals are now un-obtanium. But I’m thinking that we could substitute some 455 kc ceramic filters, which are readily available.
I like the receiver. A lot. So far it is my only real tube HB project. Encourage your friend to give it a go!
Keep me posted! 73 Bill
