Hi, I’d like to upgrade a V6, I built some time ago and which is no longer available, to a diamond drive.
As there are the same numbers of components , Is it possible to replace them according to their number ?
Ex: Replace “V6” C1 : 100nf by “Diamond drive” C1 : 47nf etc.
I can’t read schematics so I really don’t know.
Thanks for the answer.

Hello, Salim BEKRAOUI, and welcome to the forum. If you have a working V6 then you are fortunate. It’s a great circuit. The Diamond Drive is an upgraded V6, and it looks like you may interchange components according to their ‘number’ on the build doc safely. Pay particular attention to TR1 if you plan to swap transistors. The 5K trimmer might not be enough resistance to bias some available transistors. Another difference to look at is the Drive pot value. Although I don’t have both circuits on hand to test, it looks like the Diamond Drive has less available gain. A smaller pot value will give you less distortion. It looks like the other changes tighten up the bass some. I had been wondering what to put on deck for next build. I think the Diamond Drive is a good candidate. Guys please chime in with more detail for Salim BEKRAOUI or if I said something wrong.
With the new Diamond Drive, a 1N5817 circuit protection diode was used. You cannot simply replace that part as the board is designed differently to accommodate this new circuit protection scheme which is superior.
During the design phase of the new board, the coupling capacitors were “tightened up” for a more Vox-like tone. You can replace these by comparing the BOM and Part numbers. I would warn against ruining any of the pads by stressing them with heat and force during removal. It may be better to purchase a new board and then you can truly compare side by side. The differences will be subjective to the amp you are using, speaker cabinet, overall volume, and tuning.
Thanks for the answers !
