If I posted a photo it would be an image of many boxes. But then, my life began before transistors, and I've not been for even a day since, outside the presence of active vacuum tubes in use in some way, between hifi, guitar amps, TVs and table radios, all my life, valves have been present and a bunch of tubes have lingered. -Phil

We would love to see some of your tubes and boxes.

OK. Nobody needs to see more pics of 12xx7, EL34 or KT-XX. So I'll pull a few of the more unusual ones to photo and post. -Phil

and perhaps a photo of your Mustang, if I interpret your username correctly

But please include the "mundane" tubes. We appreciate all tubes.

I can watching all of my tubes every day without getting tired.

Maybe we can start a tubespotter society.

I’m new to this forum, but I do recognize a few names from Facebook groups. I just scored this pair of NOS EL37 tubes & am planning to try them in a Fender Vibrolux Reverb. I’m swapping out the NOS JAN 6L6WGB that are currently in the amp. Current plate voltage is 418v at 36ma. I noticed there’s information about screen voltage being an issue with the EL37; however, I don’t know how to measure it.

EL37 data sheet

You can check the recommended and max operating conditions depending on the tube configuration. Some measurements would have to be in circuit since a tube tester may not have all these parameters measured or displayed. The assumption is that if the correct tube types are used and the correct rectifiers are used - then everything is within normal operating conditions. Tube swapping and substitutions can work, but I always check with the amp designer or manufacturer before going too far astray.

Feelin' groovy ....

This username goes back to the earliest forums after the Web debuted. There was a transition from newsgroups, which were the home of hobby & interest exchanges on the internet, Compuserve, etc. before the Web hit. Some of the first fora I was active in circa 1994 (I built my first corporate web site in late 1993) were automotive, and at that time, my projects were SVT Mustangs, specifically a 1993 SVT Cobra that I made some light mods to, and then I bought one of the first samples of the 32 Valve 1996 SVT Cobra Convertible, which I promptly set about to seriously upgrade its suspension and other control bits, as well as to weld in full tubular ladder subframe connectors -- made it torsionally stiffer than the coupe. Fab car I had for ten years. 213 was the original LA/SoCal area code (still have a 213 cell number too). I used the username across interest forums from automotive, guitar, hifi, astronomy, politics, etc. Of course, that was from the time when the internet was about anonymity, long before social media. I've been 213Cobra for over 30 years and counting, online. Alas, I don't think I can locate any photos of those Ford SVT cars, but if I do I'll post some. I have a few interesting tubes to post, which I'll get around to in the next few days.
