Even longer tube life with quick and latching (keeping the amplifier de-keyed until reset manually) protection circuits.

Still it nice to know where
to get replacements if needed or wanted for spares.

Does DX Engineering intend to sell these tubes?

I have 25 amplifiers here that use 8877s. It is a really good tube for
amateur use at 1500 watts output.

Some of my amplifiers have 8877s with date codes in the 1970s and they are
still going strong.

With care - 8877s last a long time.

I built a 8877 tube tester several years ago to insure I can keep these
amplifiers going for many more years
