Natural Sound

[jeff1225]

Mr. Lamm liked his Russian tubes I guess because he was comfortable in what he knew about their performance characteristics. The 6C33c isn’t the most linear of triodes and has special heater and output transformer needs but it can sound damn good nonetheless. I have owned several amps with that tube (not a Lamm though) and still own an Ayon Spark that I use in my DIY active system.
The prettiest sounding amp I think I have owned though is my Silvercore 2A3 amp…you just melt when you hear it. Crystal clear mids with some softening of the frequency extremes…but that mid!!

Most set tubes last for 1000’s of hours, unfortunately the 633C isn’t one of them. The 300B, which can and was buried in the ground for telephone use can last upwards of 10,000 hours. Lamm couldn’t have foreseen the issues with Russia but I do wish he made some SET amps with more common tubes. Although I’m extremely happy with my Triode Corp 300b amps, I would have loved to try Lamm ML2’s on the Hartsfields. Too much risk now.

This is such a cottage industry/hobby, once a designer passes on, his company is essentially defunct.

I am getting surprisingly long life from the ones in my Ayon amp…not sure why but it just works year after year…

Easy. Ayon is known to use custom tube sockets with beryllium spring contacts. Magic does not extend to tube sockets, they rely on engineering ...

IMO it looks suspiciously rusty ... But I am not a socket expert!

Yes, probably it was the best 50 years ago ... Before it rusted miserably. Just commented on the photo in the link you posted.

BTW, as far as I have read, the fighter jet story is a non documented legend, there is no evidence of it being installed in actual fighter aircraft.

Then go ahead and buy some high-end Teflon socket that will then be boiled at 300° Celsius by the 6c33. I'm not forcing anyone to buy something like that. It's a series regulator tube in the mig 25 go to an aircraft museum and you'll know where it sits
