The ultimate DIY? A Stax SRM-T2!

The biggest thing is to make sure you don't over voltage any of the resistors.

There are parts of the circuit that have 4 resistors in series to make sure

you can handle killovolt swings. The original used a lot of surface mount

resistors that could handle only 250 volts each. If you use the standard rn60's

they are good for more than 450 volts each.

1/2W PRP's can handle 500v and are relatively cheap so they make up the majority of the resistor with a few Rikens thrown in where PRP's weren't available. The 5W resistors are Mills. The only resistors I'm a bit worried about are the 5.1k/1W output units which will see the full fury of this beast... :-\

Dr. G-

Please put me down for a complete setup, and I've always wanted something with an RK50 so I will plan accordingly once somebody agrees to build this beast for me. Let me know when you want funds, but I appreciate you fronting costs for now.

Thanks, Al

Damn Al, just damn. I'd offer to build it but I'm going to go out on a limb and say you'll want someone more skilled.

I thought about sending you a PM, but I am just as happy to say publicly that I would trust you with this project without reservation or hesitation, Nate. Maybe I am just uninformed -- well, I am but you know what I mean -- but other than being meticulous like you are and having the soldering and other related skills that you possess, what is different about this project compared to your current 'stat effort or many other high-end projects you have completed successfully?

Hmmm, those sweep tubes could work in an ESP amp... :)

Nate, retirement sucks.

And you did just order all that wire. :P

Sigh I think I'm going to have to pull out of my dream of a full fledged electrostatic. Added up how much I've spent on audio and it is a little bit terrifying :/ Almost 2x what I thought it was around...

Sorry for being a weak flaker guys.

You need to embrace the concept of denial my friend!

More than my takehome salary for a year (After my promotion with a 30 percent pay bump) is a little bit.. intimidating.

I think the Esoteric UX-1 has to go.. I'm not sure I can bear to part with anything else at this point in time :/

If Justin finishes rebuilding the SS-1 or when my Dynaphat (Balanced dynafet) is complete.. then perhaps the Gilmore Balanced Reference can go to the line of people with dibs on it (dreamwhisper #1).

When I bought my first amp I made a pact with my wallet I would never do that... the relationship has been smooth sailing ever since :ian:

well, i havent built anything in quite a while, and been kind of out of the headphone thing for probably equally as long... but if there is an extra board, i would really love to get my hands on it and see how cheap i could build one... hell i only spent like $4~500 on my dynamight and everybody loved it at the meets lol

Uh, extra boards? Given that the boards for this will cost more than your dynamight it seems unlikely that there would be extras just floating around.

Of course, we are dealing with Kevin "Titanium Hammer" Gilmore. :)

Like Nate said, any illusions that this could be built on the cheap should be dropped ASAP. The tube sockets alone are 160$ and the boards ~250$ for the set. Then you have to find a lot of rare parts and match them.

You forgot to mention that the boards can only have things soldered onto them with a solid platinum soldering iron. Dunno why exactly but I think it's a Japanese thing.

Also, that iron has to be blessed by a Shinto priest. And since every platinum soldering iron blessed by a Shinto priest was summarily shot into space, you need to find the asteroid impact craters and salvage the remains. Also, Lobstercunt has 3 for sale on A'gon.
