Interesting! Is the weight of that whole assembly held in place by only the friction fit of the 18 pins? Also, rather peculiar the circular cutouts on the underside, where the tubes plug back in are dissimilar in size...

So the last question: is it the same 5e3 ckt, Yes. As for current limiting; I hooked up my 300w light bulb current limiter and was able to turn the amp on. I was able to see voltage on the low voltage connection to the rectifier tube socket but the high voltage was showing 0 volts DC. I think this ...

This is more a question than a suggestion. I’ve put a bit of thought into this over the past ten years because I am very intrigued by the idea of AB2, but I’ve not done any experimentation to this point. What if you were to use an asymmetrical bipolar supply for the 12AU7 CF drivers? Let’s say you’v...

Ha! That is really cool!

Hey all, Yes, this board drops right into the HRD line of amps to replace the not so desirable OEM board, but it can also be used for ground-up builds. Gold plated pads all around. Two-layer board with ground plane on the top side, so all traces have a screen on top, as well as on bottom (due to the...

Phil, Martin,

Thank you both. Doing the layout drawing was an eye opener. In retrospect, I should have done it first. I learned so much about the process along the way. I will definitely be making a few changes for the next revision.

Cheers,

Hi All,

Long overdue, but finally done. Here is the HRD2ODS, Rev B Chassis Wiring Diagram. Please let me know if you spot anything fishy. This is my first drawing of this kind.

Many thanks,
Lou

Hi Jason, I am in the process of doing a layout drawing for this amp. I have attached an in-progress pdf, that shows the Foot Switch Jack wiring. The volume difference between Jazz and Rock position is drastic, and this is just the nature of the beast. The effect of both the Bright Switch and the MI...

Ok, here are the pictures. Let me know if you need other angles or any questions answered. https://drive.google.com/drive/folders/1T64C8g6BkK0ryELPXNavzvIEvRtm6Ayn?usp=sharing Jason, Wow, there is so much going wrong here, I don't even know where to start. If it had not occurred to you by now, you ...

It's not ods clean channel clean, but to my personal experience it's pretty clean for a lot of the volume range unlike what I hear about the tweeds... no? This was where I got confused... maybe I am ... just c...
