dual rectifiers for ST120 & ST70 amps

Hi, I am struggling with the dual rectifier V2 board. The width is too long and it hits the transformers. I don't know what to do now. I am afraid to just Dremel sand the corners down because I don't know the circuit board layers. Anyone else run into this issue yet? Also the mounting bolts do not match up with the holes in my case. ??  THANKS! Scott

I made a post about that issue within. Upgrade.  https://dynacotubeaudio.forumotion.com/t5087-st-120-dual-rectifier-upgrade

In summary. The pcb board is not multi-layer or with traces in the way. Push mount of transformers back as far as they can go. Then nibble the corners off with dremil

Thanks, I didn't see that.

Scott,
You may round/cut the corners of the PCB as there are no traces in that area. The instructions mention the following:
"If you are installing on an ST-120, you may have to round the corners of the DR board near the output transformers, there are no traces in the corners to worry about."

If you rotate the board, you'll find the holes will align with the chassis.
Hope this helps, if you have any further questions, email is usually the quickest response. I will check back here later today.

THANKS!!! These instructions were great! I am so glad you pointed me here. I was struggling some with the included instructions. Your diagrams were spot on! Thanks Scott

Does it continue to function as if it's a single rectifier amp or does it shut down the B+ supply? (I assume it won't take the other tube with it when one dies). Also, am I correct in assuming the two rectifiers should be matched or, at least, similar (i.e., no pairing 5AR4 with 5U4)
