I don't mean to be "that guy", but one of your '57s is in the '56 section

A '57 trying to masquerade as a '56? Maybe even a ribbed plate '56? Unacceptable. I'm gonna put it in the tester and juice its heaters with 117v. That'll learn it.

Lol! How embarrassing! Who would do that?!?! Get it together, Bcowen!

That'd be cool! Be sure to post a video.

I'm sure there is a viable reason for its placement. I suspect that Foton was mfg June 15th of 1956 and @bcowen struggled greatly in determining its placement. I suspect it resides in the '56 pile for first 6 months of the year and then gets moved to the '57 pile the last 6 months. Obviously, the picture was taken in the 2nd half of the year.

Being OCD is a curse @bcowen must carry and he carries it well.

There's no such thing as too many Fotons. No such thing as too many Melz either, you just need a much fatter wallet.

I am curious how many are re-soldered so to avoid the 100 hour burn in. One does not need a fat wallet for Melz if you have the right connections. I got some highly prized versions for $35 each.

I'm sure @bcowen is working his way through burning-in this stash on his Vali. I think he's worked his way through the first column and half-way through the second. He has no life, so it gives him something to do.

BTW -- I think the 100 hour burn-in only applies when using music. If he is using Marilyn Manson, it cuts burn-in time to 10 minutes per tube before they either straighten up and fly right or just quit altogether.


***Ooops. Appears that I double-posted.

I decided on a 1976 Melz 1578 to go out with a loaner amp, great bass, mids are really strong, a great match with a Tung Sol 6080. I will include a 57 Foton and at least one Sylvania.

Nice Knobs!

Nice Knobs!

I had something more pewter looking on it before but decided to go chrome to match the rest of the hardware.

 

[Ripper2860]

I think @FLTWS meant to post that in another forum.

C'mon and give me a break. It's not easy being me.

The ones that have an "RS" on them. So, 3 I guess? I have a couple on the desk that I rotate in and out which have been resoldered too. The problem with these Fotons is that resoldered or not they last forever, so no big need to go on a resoldering rampage. A couple months ago I retested the first rib plate I got (a '51) that probably has 2k hours on it and it tests exactly as it did when new. Of course it wasn't new for long because I burned it in for 100 hours right off the bat.

Oh please. It's much easier for you to organize all seven of your tubes.

 

[Ripper2860]

Organize? Pffft. I just stick my hand in the bin and pull out a random tube leaving my fate to the tube gods.

I was very curious what "RS" stood for. Now I know.
