So during the first run of the amp it was cooking along pretty nicely for about an hour. I switched it from tube rec to solid state and played the set (about 30 mins) I then powered the amp off and switched it back to tube rec, turned the amp back on and no sound though all logos lit up. The HT fuse had blown. I am going to go get some fuses as I didnt have any on hand but wanted to know your opinion on what could have happened.
The amp is built completely to spec using tds transformers

The HT fuse is frequently power tubes or rectifier problems. It could just be a coincidence that you changed rectos.......but you might want to start there when you get new fuses.
Good Luck

Hi,

Do make sure the HT fuse is 1A slo blo.

It can be a bit triggery if smaller is used.

Do report back on this, esp if the HT fuse still blows when changing mods between tube / SS rectifier, and vice versa.

I havent experienced this, even toggling it back and forth. Not sure if there's some surge at play when changing the modes, will look into it

Also, since this was a kit, did you install the cap/diodes on the recto tube socket? Would be good to protect the tube recto.

Thanks!

it hasnt blow a fuse while playing yet but yesterday I powered it off and switched it to 15 watts. I turned her back on and started playing for a bit and then the sound slowly faded. Checking the fuse it looked browned as if burnt but did not fully blow. I replaced it and went back to standard full power and no blown fuses though played for 45 mins straight....what gives!!
