Stuart, I posted some videos about soldering accessories on my channel recently, and a review/teardown of a really cheap soldering station that is light years better than what I had to work with as a teenager in the 1970's. Perhaps you or some of your viewers will find the information helpful. I didn't monetize the videos so there shouldn't be any ads either.
Why does fender Ultra Linear amplifiers have more headroom and less distortion? I'm not sure why amplifiers use slow blow fuses instead of fast blow fuses?
The whole reason for ultra Linear is to Reduce distortion, mainly it’s a Hifi thing. The big Fender amps which are Ultra Linear are super clean with loads of headroom . Certain circuits have a high inrush of current or peaks during operation they would use slo Blo fuses or T timed as we call them over here. I hope that helped your question. Trev
@@trippntrev Yes in USA they have different slow blow T timed I think its in Nanoseconds rating. Since guitar amplifiers have a high In-Rush current that is why they used slow blow fuses that were T timed at a certain timing. I'm not sure what the T timing is but its based on the how many In Rush Current Amps it seems?
@@trippntrev The biasing is 20mA to 30mA also for Fender Ultra Linear? The Ultra Linear use custom made output transformers that have more TAPS for the screen grid biasing + positive voltages it seems.
@@waynegram8907 you can just guess plate current you must calculate the dissipation , however I have found the bigger linear amps work very well at lower dissipation with no crossover distortion and tons of headroom

Thanks Stuart
Straight to the point !!
Love the videos
Cheers Dave
Polite, and to the point, Stuart. Well done as always. Cheers!
Thanks Alex
Nice one Stuart...Easy to follow, thanks for the tip..Ed..UK..😃
Cheers Ed
Always good information. I suppose this would be the same idea for most amps build like this.
Thanks for your time,
Mike

I'd be interested in that can you link us in? I use the Duratool desoldering staion which is SO cheap and works fairly well.
