I just boxed up your order. Thank you very much for your support of my business and me.

I noticed that you were one set of binding posts short. There was only one pair (i.e., one red and one black post) on your order. I'm happy to ship your order that way, but since it looks like you're building a stereo amp, I thought I'd ask if you'd like me to add a second set. It's always more fun to get everything you need at once.

I've tossed you an email about that just moments ago.

Tom

You got it! Enjoy your build. I hope we get to see some build pictures here. No obligation, but it's always nice.

Tom

I have been working on 2x 5CH Mod-86 Amps for my LX-521.4 speakers.
Tom helped arrive at a customized design for this speaker. Custom transformers from Toroidy.pl are used.
Heat sinks are from HEATSINKONLINE and chassis is Modushop Pesante.
As others have vouched before, Tom's support and guidance is exemplary.
Prompt responses and detailed guidance and willingness to discuss everything from electronics to suitable parts#, tools and mechanical design make it a pleasure to work with him on this project.
All modules were tested using lab supply and were functional on first power on. This again points to the reliability of the design and detailed instructions made available.

Posting some pictures of work in progress. Cabling and mechanical assembly are the next steps.

Looks very nice! Are those heatsinks big enough even for the woofer amps?

Math says those heat sinks are enough for music reproduction.

I love those modular Modulus.

Tom

Thanks @poseidonsvoice, I can't wait. Initially it'll just be with a pair of C-Notes that I built for practice until I get/build my real speakers (CSS Audio P215s probably). Then I'll finally have my completely overkill office stereo system (or at least the beginnings of it!).
