Thanks, Martin put a lot of thought into all the extra features on this amp layout. I just had to build one.

Martin could these improvements with grounding also go with a Princeton layout?

Looks like you handled that project just fine! Looks nice! And nice picture of the front panel showing where the dang wires for the tremolo pots get routed! For some reason it is almost impossible to find a good shot of that. Mike Thanks Mike, When I have it out of the cabinet I will have to take s...

After re-biasing these are my readings My voltages are: A B+1 411vdc B B+2 408vdc C B+3 327.7vdc D B+4 274.5vdc This time I took the plate voltage reading from 6V6 pin3 which is 409vdc and the red test jacks 19.2mV 19.6mV Total Power in watts on Tung Sol 6V6GT tubes. 409 * .0192 = 7.85w 409 * .0196 ...

I have a doghouse board cover from Mojotone installed. When i took that pic I was still wiring. The mojo cover is plain steel not anodized. I'm using a EH 5U4GB Rectifier My voltages are: A B+1 397vdc B B+2 394.2vdc C B+3 316.2vdc D B+4 265.2vdc Using the three test jacks in back with my DMM black i...

I finished building my Deluxe Reverb using MM Layout. It turned out better than I hoped. Big Thanks to Martin for his work on these layouts and my questions. Amp is very quiet and the only trouble I had was V5 tremolo ticking. I tried the Fender-Service-Bulletin-9 .01uf cap but still did not fix it....

If you are hearing humming with standby off through your speaker you may have the OT misplaced in the magnetic field lines of the PT.
I had to move my OT to get rid of it on my express build. https://ampgarage.com/forum/viewtopic.php?f=1&t=34638

The OT is a 1750H, which is also supposed to match BFDR spec. In a recent thread, the wire colors on a Hammond transformer were found to be reversed wrt primary-secondary phasing. I found the same in this case, which is odd since the exact Fender PN is referenced here too. Hammond's documentation (w...

If cost is no concern NTE is a great product.

I found this useful in explanation: https://www.electronics-notes.com/articles/electronic_components/capacitors/ceramic-dielectric-types-c0g-x7r-z5u-y5v.php However trying to get Class 1 for all the ceramic disks is not easy to find. Just wondering if you had a mix of class 1 and 2 ? Here are the Ma...

On the ground scheme pic it states "PI and LDR NW Ground" but I do not see a ground lug to the chassis. Where do you attach too? Also the Ceramic Disk caps, what brand are they and who who did you source from? In my my early stage build I only count 6 ground lugs. - Reverb Tank Ground - BC- Ground -...

On the rectifier socket you used diodes to protect a short from the rectifier to the PT output.

The wires from the PT go to pins 7 and 5 which are unused and from there the diodes connect to pins 6 and 4

What diodes did you use?
Are they IN4001?

Safety should be first priority Have protection for your eyes, and one hand rule for probing High Voltage DC (USE MINI GRABBERS) and learn how to discharge high voltage from Caps. New builds use a light bulb limiter at first start up is a must have tool on your bench. Here are a few items for the wo...

I have added two guitars to my collection. A Gretsch G2627T Georgia Green with upgraded bridge Tone Pros TPFR Roller Saddles and tuners Grover Roto-Grip Locking Rotomatic 502 and the Godin A6 Ultra 2nd from left in cognac burst. I have been itching for higher end Gretsch guitars but can not afford t...

I have my solandfa DR Kit but that is all so far. Still putting a bill of materials list together. Hoping for good Black Friday deals.
Thanks Martin for all the work you put into this.

Thanks for the info. I think the Hammond 167R5 transformer voltages will work my equipment. Mother nature 50mph wind gusts decided to snap one of my fence posts today which is going to delay my plans for new stuff. Also, I have been considering adding tubes4wifi m125 mono blocks to my pioneer SX1050...
