These tubes have been around for years and used into early 90s. I still have a Heathkit SB-101 and a spare set of 6146s somewhere. I would like to get it on the air again but have to find or make some pullies for the tuning capacitor which disintegrated over the years.
Back in a day I had one of those EICO 723 (seven drifty three), there was a reason they were called "seven drifty three", you had to find the station again you were having a QSO with after you got done transmitting. (exaggerated a little).
One thing about tube finals, you didn't have to worry much about high SWR, they were forgivable for most part.
Good luck building your vintage station. We'll have to get on the air with these rigs, specially in the winter just to keep the shack warm. Hi Hi.
