Just like the vintage unit, this enables a bandpass filter from 50Hz-15kHz.  Looks like this (click to see big):



Since there are electrolytics making part of the filter here, I did a lot of work to ensure that those selected most closely resemble the performance of the vintage units.  I compared a stack of different caps in mine against 5 different vintage EQs and eventually settled on the Elnas that you'll see in the kit.

It is indeed a 500 series module, so you'll need a rack of some flavor to plug it in to.

Hi,

payment sent for a kit! Will the gar2520 offered by ClassicAPI be OK for the TB550A?

Thanks for this great project!

Hi Matteo, thanks for your order!  That will go out today.

Yes, the gar2520 will work very well.  Remember that you'll need two of them.

Have fun with the build!

$410 without output transformer and the two 2520 Opamps ?

Seems ridiculous expensive!

I agree, it is an expensive kit!  There's just plain a lot of stuff in there, those Grayhills being the most significant bit.  I should post some pics of the guts.

Yeah, let's see the guts! :D I will be down for at least two. Had some car and computer problems that have put a pinch on me $$ wise, but as soon as I can safely do so I'll be ordering a pair. I'm super pumped for these.

Hey, guess what? You have an option here. Not to buy!  ::) Hurray!

BTW, did you ever price real 550As?

Price out the parts , and add some research & design
and decide if it's worth it to do it yourself

I don't know anyone else anyone brave enough to take on the mighty 550A , Bravo !
I'll buy one eventually , once i save up
but I never hoped to own [ or want to pay the price ] for a real 550A

And for me i think this follows where good quality D.I.Y. is usually 1/3-1/2 off
the authentic product , quality costs money , no way around it
