Bogner XTC 101b questions...help needed!

Post by Luca » Sat Mar 05, 2016 5:42 am

Hi guys, I tried to nail the tone of Bogner XTC in a 100w stock plexi chassis.
I put a new PTP board with 101b value and I'm pretty happy with the sound but unfortunately I'm not 100% satisfied with global tone, and since I have no confirmed schematic I'd like to ask some questions.
My main problem is I have to much muffled bass frequencies. I found high freqs to be ok to my ears but E and A strings disappears when I play a chord. I remember of a deep, precise and focused bass on my XTC that I don't be able to find in this clone.
(I have to said in the past I own a 2008 101b, so I'm pretty sure of what I sonically miss in this clone)

- I have 50/50 capacitors everywhere (pre amp, screen and main). Have I to lower the preamp values to 33 or 22uf? What's the impact in sound?

- What are the values of plate resistors of preamps tubes? (I mean dirty stages only).

- Last but now least and I think the most important: have someone a correct draw of NF network?

Thanks a lot.
