Feeler: 6550s GE Sylvania Tungsol etc
I'm trying to figure a value on the following 6550 tubes.
Sylvania.Phillips strait side used but test strong
Tung Sol old USA production used but test strong, Various branding (RCA, Tung SOL Sylvania) .
All of these were slated for the SVT I never got around to replacing so all are groups of 6.
Also have 4 Sovteks pulled from a McIntosh 275 which were said to be fresh.
I have GE and Sylvania 6CA7s and Mullard EL34s but those are probably of more use to guitar and HiFi aficionados.
Off on a hunt for PRE-CBS P bass parts so something has to go, maybe these not sure yet.
