retube VTL amp

It's time to retube my VTL MB250. The unit is 5 years old w/ the original tubes. I just lost one tube and so its time to retube.

This will be my first to completely retube this amplifier. In fact, it will be my first time to retube an amplifier with so many tubes, 10 tubes per side.

To me, it seems the easiest thing is to purchase the complete set from VTL? If you have purchased tubes from VTL, I would like to read your thoughts, pros/cons.

Any advise with purchasing tubes from another vendor? Any recommendations?

Zaikesman - thanks for all the tips with tube install & debugging. it will come in handy.

can u elaborate on "less tubey" about using KT88 instead of 6550. i hadn't considered anything but 6550. i recall reading somewhere Luke Manley recommends only 6550s for his VTL amps.

i will experiment with the input tubes. very good idea.

thanks again.

Zaikesman - thank you. the mb250 runs in triode only, so it is worth considering & also to get a different perspective. "tubes rule"

btw ... it will cost about 33% more to get the tube set from vtl for the mb250s.
