Thanks, sorry, I did not realize that the original title was a vendor name.
Running joke among friends in the day, to go to the tube store ! (yes, these places did exist... Elmhurst Tube and Electronics, etc., generically... "the tube store")
We'd pack up the car and take the family to the tube store
A new pair of sweep tubes for Mom's TV soap-operas !
Some 12BT7's for the pre amp of Jenny's suitcase record player!
Dad would buy a quieter detector for the shortwave, so the European polka stations would be hiss-free!
I'd get to buy some JAN 811a's to power out an RF oscillator and screw-up the neighborhood's TV reception trying to send morris-code to Chile'
Ah, the nostalgia, the tube store...
Anyhow, I'm starting off with some JJs and found a few locals to swap and roll with in the process.
If I don't find satisfaction in the effort, I'm going back to the powered planars and a bit-bucket source.
