Hiyya - capacitivewaves - 06-26-2024

Hey there
Im Sarah, from France. I've been repairing tube amps since 2016 and occasionaly building some, mostly copying iconic designs (and their flaws Smile ). So far I built a JTM45 with more low end, a 5W mesa-nspired amp, 2 Hiwatt-50W clones and a few low watters based on Rob Robinette's micro Deluxe. While roaming on the internet I came accross London Power Power Scaling and I ordered all 6 TUT books. I am looking foward to reading them all but I only finished TUT for now and it made me want to experiment a lot of stuff I am not very at ease with (hello solid state).
For the moment I'm building a 2-channel amp with boost, reverb and FXloop for the largest reheasal place in town. Big challenge as I'm trying to implement solid state circuitery for switching in there. I built the mosfet FX loop as in TUT fig 7-27 and I'm pretty happy with how it turned out !

Happy to join the forum to discuss all of this with you all Big Grin 

Cheers !

Hi Sarah

Before you build that studio amp, get into TUT3 and see the best way to lay the amp out for lowest-noise and best note articulation. You can commit a lot of sins building low-gain amps but higher gain needs better grounding and wiring.

The Galactic Ground method shown in TUT3 is based on science not voodoo and can be universally applied to all construction methods and to all technologies.

Have fun and welcome to the forum

Hi Kevin
I read chapters 1-4 of TUT3, I was indeed going to use the Galactic Ground method. I'm also going to follow your tips on best quality parts and mechanical assembly.
Thanks
