Took a short bike ride this morning finishing in the low 90's. It's 103 now so glad I took a coffee break.3 points

Since I started trying different tubes on my SRX Plus I've noticed that, while the amp is dead quiet with some tubes, some tubes will result in audible hum with no input signal present. After some reading and experiment I decided the hum is most likely caused by leakage current between the heater and cathode of the input tubes. I decided to elevate the input tube AC filament supply. The photo below shows the filament elevation circuit I added this morning. The 12.6vac filament is elevated to about + 56VDC reference to ground. The amp with the same set of tubes went from a bothersome hum to dead silent (knock on woods)!3 points

@mwl168, I found exactly the same thing. Once I elevated the heaters, the hum was eliminated completely. 12AT7s are at 60V (voltage divider off B+ rail) , and 6SN7s are at -340V (tied directly to B- rail). In all, I did 4 things to make mine totally silent: Used voltage divider to elevation the filament voltages. +60V for 12AT7s and -315V (or in my case, I just tied it to B- so -340V) for the 6SN7s I switched to different set of tubes. The ones I started with just hummed. After switching, much less hum More careful grounding of components Finally, to get rid of slight hum when volume control was at 11:00 to 5:00 position, I switched from a 50K pot to a 10K pot, which totally eliminated any hum when the volume control was in the mid/high region.2 points

I studied classical guitar in a Segovia influenced studio for 7 years (many of the instructors had attended his master classes in Madrid). We all had great respect for Bream and I always aspired to have a pinch of his wonderful tone. I never got to see him in concert but I listened to The Art Of Julian Bream (and the wonderful Hauser guitar he played on it) constantly. RIP1 point

I switched from Logic to Ableton five years ago and I feel pretty comfortable in it. I watch plenty of tutorials and still think "ho-lee-shit. That's how they do that." all the time, but that's part of the fun. I use it on Windows, which is total blasphemy and I understand if none of you want to talk to me ever again.1 point

I'm a fan of a few of the Cartiers and that is one of them. Bought the wifey a Tank Francaise for our 20th and gave it to her over a late lunch at Tony's. She loved it. HS1 point

The Santos has gotten all of the attention lately and the tank is the tank. But they do have some really nice dress pieces that are currently overlooked.1 point

RIP.... My son's guitar teacher had played with Segovia (not on any big stage); and while he idolized him, he also had mentioned Bream as the "next generation's leader" - pretty sure those were his words.....1 point

Yeah, thanks for trying it out. I look forward to your continued thoughts. I actually have the full suite of emulations from Arturia, including the CS-80, will have to get back into it. Just stuck playing with the Prophet 6 these days. The Prophet 6 has velocity and aftertouch, but the aftertouch is almost a plateau, like a soft step function, which therefore makes it not very expressive at all, so I hardly use it.1 point

my 1st post is a sad one. RIP Julian Bream https://www.nytimes.com/2020/08/14/arts/music/julian-bream-dead.html0 points
