I've been to tube limbo AND solid state limbo.
That was the reason I unloaded a ton of vintage stuff back in around 2005. Everything that didn't work or "almost" worked - OUT!!!!
On the 6922 front. I was using EH in my CJ preamp and they were going every six months - yeah you read that right!!!
I switched over to Gold Lion 6922s and I've had the same one in there for almost two years now. It's still going. Give that a try before you dump your preamp.
But I am liking more and more just a simple preamp. Or perhaps more of just a buffer and less as much a preamp.
I don't understand why your 6922s only last for six months! They should last for 5-10000 hrs. Is the heater voltage higher than 6.9V (+10%)?
For me it comes about every few months, or when the prozac prescription runs out. Just joking! I use Adderall. just joking!
But, seriously, i just start working on a new project and "tube amour" comes right back. cheers.
Come into the light DAK, COME INNNNNTO THE LIGHT~!!!
Three seconds after the voice in my head says "well this solid state amp is JUST as good as my tube gear". BANG - maybe Jim McShane got some new MAGICAL tubes in stock!
That you have to open up equipment and be comfortable with exposed 500 volts.
Didn't use to be like this when you could just call your neighborhood RCA repairman to make a home visit.
to touch exposed hi voltage areas with your bare hands. Actually, i have been buzzed a few times but the worse was with a Fisher amp with a voltage doubler and the brainiac who "rebuilt" it did not insulate the "hot" cap. This happened in my early tube days. During the first power up i touched the cap to see if it was hot and needed to be replaced and boy did i get a nasty shock. but, i am still here so i would not worry too much about getting shocked as the currents associated with the hi volts are not very much and as long as you have rubber soled shoes and and are nowhere else grounded, the risk of injury is not likely.
It was early in my audio days and I was fooling around with a Dynaco ST-70. Using a DMM I rested my finger on something. It was a shock that made me realize this stuff really CAN kill you.
If I did that today it would have killed me.
We used to have cattle and used electric fencing. Sometimes you would touch it when closing a gate or incidentally while working around it. But that shock will make you scream and lose control of your muscles. Fortunately, the current carried by the fencing wire is only a few milliamps so no real damage. But it really hurts.
