Re: Plans to build a handwired JTM145 clone with added presence pot
Thanks for the advice about the star grounding! The longer I look at the shematics the more i ask myself why C19 cap is connecting the positive high voltage with a realtivly small capacitor to the cathode? Also i ask myself, why so many electronic elements have been added to the input, cathode resis...

Re: Plans to build a handwired JTM145 clone with added presence pot
Thank you for your opinion! How do i add two different grounds? Arent they connected all to each other normally? I didn't have a general consideration about the design layout. I just wanted to make it as clean and the connections as close as possible. In the circuit there are many connections with u...

Re: Plans to build a handwired JTM145 clone with added presence pot
I updated the plans again regarding the change in circuit and also changed MV Type 3 to linear pot. Is everything correct now?

Re: Plans to build a handwired JTM145 clone with added presence pot
Did I add the two types of MV and the presence pot correctly?

Plans to build a handwired JTM145 clone with added presence pot
Hi all, I plan to build a handwired JTM145 clone with added presence and master volume pot. As foundation I took the plans of Matec from this forum. I'm sure that I probably did some mistakes in the design. But I want to ask you for early feedback to analyse if I plan in the right direction or need ...
