Hi! First sorry that not in german but noone really would like to read my poor german
Recently I build a SLO50 with Tube town transformers and in general it is working quite good, zero hum, very low noise, very stable but I have some doubts regarding tone. I've never played orignal SLO so it is hard to tell is it good or not but here are my thoughts
1. Bass response is weird (to much not very tigh bass) with no possibility to tweak it without any eq at input.
2. Weird mid range - when I'm playing with attenuator it is not so clearly audible but when I'm playing loud something odd is happening with mid range (is hmmm... woody, don't know better description). and it is getting even worst warmed up (after 2-3h of loud playing)
I read on forum three advises for 50W build but without deeper explanation
1. Change NFB resistor from 39k (I guess it should be enough to connect it to 8ohm out rather than 4ohm) to get the same level or maybe You have other thoughts?
2. Rise voltage because it can get to "browny" whatever it means and what rise voltage really means
any one tried it?
3. Change PI coupling caps to 22nF for better bass respond (is it true?)
4. Also I read somwhere that depth mod can create some issues.
Do You have any advices that I can check for such problems?
