Reiner Amplification Megathread

Ohmygoodness, I see that now .. thanks, silky. And right below that, "This will be blasting through a Heritage 810 soon!" .. I believe that's _my_ 810 he's talking about. Definitely very much looking forward to that! My neighbors and I are going to love it.

Thanks, silky smoove, for pointing me over there.
 
Hi, JGR - just making my regular weekly Friday check-in with you to see how you are coming on the Studio 1200 amps!?

I hope things are going well for you.

Hi Eric,

Got your DI and power module installed and wired up earlier this week - just need to drop the board in and wire it up. I'm celebrating the big 40 this weekend so things should probably come together by next weekend.

Happy birthday! You know you are now getting very much into the downward slope, don't you? Better hurry and finish those amps!

Fantastic! That looks awesome! I can't wait to receive it and put it through its paces when I plug it into my Heritage 810!!

Does this mean my amp shares its birthday with its creator?

I was actually thinking about that today when I dated the inside - mine is Tuesday the 31st, but this one will go down as the B-day build!

That is one full-looking amp case.

What are the tube sockets mounted to? I have a number of amps/preamps where they're mounted to circuit boards -- haven't ever had an issue, but it used to make me nervous when swapping tubes. Speaking of which, *if* I ever got one of those amps, no matter how good it sounded, I would be unable to resist the geek-urge to try different tubes in there. Not necessarily pricey ones, just different ones...

While I'm asking dorky questions, what's the big red thing -- a transformer? What about the smaller, octagonally-shaped red thing next to it?
What's this button do?

One end of each socket is mounted to the thick G10 board with a SS machine screw, washer, and nylock nut. The other end is secured with a SS machine screw and reinforcing washer to a metal standoff that is secured to the chassis with another SS machine screw. Those screws get Loctite in the final assembly. The sockets I use hold the tubes nice and tight, and the structure is very robust. I don't like sockets mounted to PCBs. Big red thing is a transformer. Little red thing is a ferrite.

Edit: Charlie beat me to it!
