I can understand bypassing the thermistor . I use a delay timer to bypass the thermistor in my hybrid amp . A simple test is to measure the AC across these things under load usually shows slight volt-drop . The rest of what you are doing seems pointless . The fuse bypass is downright dangerous !!!! I have plenty of huge transformers and chokes that will probably put what you have used to shame (ever seen a 3H 1A choke ?) but I rarely use the large items apart from in breadboards . I currently run 100VA 300V 45 ohm transformers for HT with 2A3 monos which are more than adequate and run cool in operation . Wire I use is 1/0.6 for small signal (23AWG) , 19/0.2 for HT and heaters (20AWG) , 19/0.25 (18AWG) for filaments/mains wiring and 19/0.3 (16AWG) for the output transformer secondary (all silver plated copper/PTFE) . I hold stocks of silver plated copper/PTFE all the way down from 26AWG (1/0.1) to 10AWG (37/0.4) but don't feel the need to use anything this thick inside a valve amp
