Received my Blue Mez boards (and relays) today, and they look fabulous, better than pictures!!!!. Thanks Tea-Bag!
Mine have arrived as well. Many thanks for this, Tea-Bag!
Excellent,
Still boards available, and Ed Lafontaine is providing a GB on matched LEDS and relay set's. A good deal if you don't have parts yet. He is closing GB tommorow I think, so act quick!

Great,
Read your construction pages years ago! It was a big help getting me off the ground.
I hope you enjoy this buffer. I have been really pleased wit it.

Glad that you found my Aleph-X page helpful! I'm still learning and at times still feel like a complete noob. My ability to copy designs and populate PCBs is often far ahead of my actual understanding of how/why things work.
I'm looking forward to getting my new preamp up and running! Thanks for your efforts!

In an Avro X powered system that will be? It will be nice to hear back from you after initial tests. Regards.

Indeed! One of the DCB1 preamps is intended for my 150w Aleph-X amps and the Avro open baffle speakers. One of the other boards is likely to become and F5 based integrated amp to reduce "box clutter" elsewhere in the house.
I still have a few XO changes to make to the Avros, and at some point am interested in swapping the IRFP9610 input differential in the Aleph-X amps with 2SK170 JFETs. I will be happy to provide an assessment when I get everything up and running!
Good luck then. I guess you are aware of the popular hot rod and film cap mods to evaluate at a point too.

Yes, I am aware that they exist, but haven't closely followed the details. I'm behind in my reading...
Just make it standard, and we will be here to give you tips to evaluate when time comes. To appreciate small changes or not, has to be a step process anyway.

Ha! Isn't that what DIY is all about?!? 😀 Countless hours of listening, tweaking, listening again, measuring, tweaking, etc. I'm not sure that I'll ever be "done" with anything

Got min too! Had to pay about 50 bucks to the danish customs though. Import duty, I think they called it. Bit of a bummer, but when the board is populated, that is easily forgotten, I think.
