[Central-Electronics] 6550

[w7fe]

When buying replacement 6550's for the 100V/200V, be sure to get ones with 
the shouldered glass envelope.
I have found that the ones with straight-sided envelopes turn out to be too 
tall and will interfere with the RF cage cover.

I bought a pair with the shouldered envelopes a few years ago from the 
Russian guys who claim to be manufacturing per the original Tung-Sol specs 
and use the original box colors and artwork.  They have been working fine.
