Awesome info Stajo, the 6V6 pre owners will dig it. Those ΡΑΔΗΟ Russian NOS are nice indeed. Maybe the 7V Vh higher temperature made them ding a dong a little more. I have some, sound is good in all but hiss may differ, they can be bit of a gamble if buying only two. I find them powerful enough yet "melodious". Good remedy for bad tweeterzzz.
Dutch Philips was Miniwatt 6V6 one of the loveliest I had tried. Creamier than VT107A maybe bit colored for that but very enticing when still powerful clear and quiet.
On the ship. A full day of hard negotiating my *** off and a son with 39,5 C fever says this day is a done day. Even if I did win the negotiations😉. I must say that this test is a bit unfair because my amp is high sensitive and the Focusrite Pro outputs more then enough rms for it. So everything I put inbetween is only gonna worsen the sound, and it does clearly. Furthermore its an untuned unisolated breadbord test rig but that taken in account its not bad that I still sit in the sofa with some of the samples. 6g6g I could almost let be there cause it colours very little. Lower mu also so... but anyway it was an interesting experiment.
I've never seen a Philips 6V6. Could they come from Australia? Philips bought a production line down under in the 1940s.
The valves and Metaxa took off the edge of the day I hope. 😉
High gain chain does not help the weaker constructed bottles but hey its more obvious test bed for ding and rattle so to know what to expect as better or not that good in any other gain scale. Maybe the 6G6G could be alright for echoes also when say in a normal gain normal sens speakers situation after all.
Theres a first time for everyone isnt it? Well I'm not the biter of calendars but if you want tube history you can talk to the boat owner currently in hospital. Hold up almost any tube he'll tell you where its made, by whom, when and who branded it ADHD square

Got a bunch of different Philips USA. Unfortunately they are all upside down. Added a Sylvania

Ah crap the SSHVs is starting to smoke the table. Addictive creatures. Gotta bypass the nice experience for a while...
Got... ehum... to many. I could ofc try some samples out for the keen one. Did so for George.
Not around anymore unfortunately. Stayed for a while back then but belonged to a friend and I returned them. Sad thing is that he probably lost them in some storage room clean up since then.
I see no sinks so the metal cube became a furnace? What you burn on each shunt, 40mA at 320V?
Same config actually. It was a gamble slipping them in. Started with 12,5 v on the filaments 🙂
Its 5 k load, can be higher and 320 from the sshvs. Silmic decouples and 680 on the cathode. Output couplers could shape up. Will post a pic of the mess from phone. Rebuilt it in 180 when I came home on the kitchen table.
You gonna become the NOS ding master tester some day if people discover your stash and wizardry 😀
