Tube stereo sounds -smaller- after being on

@yaluaka I am fortunate like yourself to have a real love for the music.

I got to a place with Source (30 years ), Power Amplification (20 years) and Speakers (20+years) that I have been loyal to for the years bracketed.

These are the foundation to delivering to me a musical encounter just how I like it.

The Mechanical and Electronics of the Vinyl Source has evolved over this period but the Source Material is collected since the early 80's.

I love to see creativity around HiFI especially the Vinyl Replay and get caught up in a variety of not too commonly undertaken experiences. This could easily be interpreted as I am a 'equipmentphile', but no, this is just an extension of my enjoyment of musical replays and is also a social activity as it takes getting out and meeting with others and in some cases witness the end product of an individuals skill set.

I was sure and am now quite sure you are a individual, who is without snobbery towards how a musical encounter is to be created. I would have wager on, there being the odd component in a Device you are using, that is known for its sonic character, and the idea of parting from it will be a real bitter pill to swallow.

For me the component is Valves, but I am not a under the hood delver, so other parts are out of bounds unless an EE is at hand as a guide.

@yaluaka , I'm all for tone controls, digital EQ to be specific. That piece of equipment does not belong in a home HiFi system. You are obviously enamored by old stuff and perhaps old commercial stuff. Technology moves on. 

I am not the only one who thinks this way. I am just more vocal about it. I am all about the most accurate sound. I am afraid the equipment you have is not going to get you there or even remotely close. You are entitled to be all about whatever it is you are looking for so don't listen to me. I am the resident  PITA.

Hey Mijostyn, everybody has their mindsets. Some people think the world is flat or the US never landed on the moon. I’ve been making records for the last 40 years, before cd and digital. I was around when cd’s were going to solve everything, and digital recordings were going to be more ‘accurate’ than analog. I’ve worked on all sorts of pieces of equipment. I’m not saying this because I think I’m an expert, far from it. I have so much more to learn. I’m just saying this as a background for the concept, that in a recording studio and mastering lab, analog eq’s are held in very high regard. And a lot of vintage equipment has great monetary value and is even replicated (to some extent) as plug ins because the qualities of that gear is treasured. So you know what you know, but I don’t think you should discount the idea, because you feel you know something, that it’s true. Not to sound like Donald Rumsfeld here. 😂

Have you tried testing and/or replacing the rectifier tube with one tested to new spec?

The 2 hour time period/demise in sound is what should be telling you/us something, but what is that?

Hi DeKay, I've been in Mississippi last week, so have done nothing. Someone suggested the rectifier tube which is a good suggestion. I don't think I have a spare. My EMT turntable however, needs a power converter so I can take that out of the system and use that converter which is a high quality one and switch out the Chinese made one that came with my amp. I will do that and report back when I have the time. Thanks again everyone.
