Build is complete, engaging firing sequence.

Wow it looks fantastic! Lead dress is quite impressive!! Have you recorded a clip so we can enjoy the sound of this beauty?

Cheers,

Fred.

Great stories indeed!

Power section almost completed. This build is moving slower than I wished, but the journey is a lot of fun!

Quick question : on #40 layout, bias calls a 3k3 droping resistor. I will be using a Fender A-036958 PT with a 60V bias output winding. On Xtian's HRD to ODS conversion schematic he uses a 1k5 droping resistor but he's also using the 60V supply to power the relays. What value would you suggest for t...

Shocked yesterday when I read the news. He was the common denominator in all the great musicians I loved for tone and expressiveness, way before I heard about his amps or knew about the man himself. I got into building amps because of him, studying his ideas and designs and chasing those fantastic t...

Hey Bepone, you are full of surprises! Love to hear about different tubes on the power section. On my Dumble journey that started a few years ago, I bought a ceriatone Dstyle 20w from a friend. I It was really deceiving, clean sound was ok but very flat and drive was barely what feels like a Dstyle ...

Not the prettiest job, but it should work properly and I have a good clearance under the terminal.

@Richard1001 yup I want to be cautious with the mains wiring as well, hence my question. In this build I chose to use a single 3 position switch that does off, standby and On. So I only have 2 SPST available. I realize there is always some improvisation in a build. @brewdude, it is never too late to...

Moving in slowly... I have a question about the use of a 3 lug terminal for the live and neutral connections. Is there any code, precaution, I should follow beside the obvious? Do I need to raise the terminal so it is further from the chassis? Do I need to isolate it from the chassis? I have seen th...

@Martin, @Richard1001 thanks for the clarification
.
@tony an IMG is worth a thousand words, and maybe more if it is a pic of Mr Dumble's work

@bepone, name a price

Got the RG59 in place, enjoying every bit of it!

@ChopSauce, thanks for the reference, I did not know there was a tool for aluminum sheets. They call it "grignoteuse" in Quebec as well, but the English word is nibbler. @Richard1001, thanks for the info ! Does the thickness of the aluminum sheet matters? Would the aluminum tape and 0.5mm aluminum s...

Hey Richard1001, thanks for your feedback. I bought an aluminum sheet that I cut with a small sawblade, it was a nightmare to do, took forever, result was not super clean... I tried to put it on top of the a running amp and hear if there was any difference, but could not tell. is it only to isolate ...

Drilling completed, let the fun begin!

Hey ChopSauce, thanks for the kind words! @talbany, I will build a bread board ODS size, I feel like there are so many combinations and I don't build that many amps to explore as much as I would wish. On my build list for 2022, I plan something like this in order to play with caps orientation and re...
