sweep tubes and audio application?

Thanks!

I appreciate the clear and concise explanations. Just the info I was looking for, no more no less.

I've come to despise ham radio explanations on certain information. They are almost always too wordy, and poorly written. Often, in their attempts to appear intelligent and articulate, they achieve neither.

Thanks again

My Acoustat servo amps for my AcoustatX speakers use 4 6HB5 tubes per amp, and it's also an OTL.
Made in the mid 1970's ,they have stood the test of time.

So using TV tubes isn't something new.

I have Dennis Had ( former owner Cary Audio) Inspire audio amplifier he built me a few years back. Features 6JM6 Compactron tubes. Picture at link

love this little amp and actually prefer the sound over my other Dennis Had Inspire amp using EL-84 tubes,
A bit unnerving buying a new amplifier that uses tubes that are no longer made but the whole demand supply thing is in my favor. I don't guess a lot of people have TV's around still using these tubes so as of now easy to find and cheep. Just this week I won a few NOS 6JM6 tubes for UNDER 3.00 a tube so I can by enough stock to outlast my amp.
I love the look of the wire connected to the top of the tube and I love the sound. I was told I should get 10 years out of a set of tubes.
