Alembic F-1X needs repair....

I've contacted Mica @ Alembic. She wanted to know if the home remedies worked.
Waiting for a reply.
I'll try replacing the tube and see what's what. Still the issue with which tube fits into the shield.
Probably a JJ 12AX7
Thanks for the support & help.
to be continued....
Well...I dug my SWR Stereo 800 out of the dead pile and hooked it back up with my Alembic F-1X

WOW!!!! Sound is big and normal.....and Beautiful!
Been test driving it this last week.....My guess is it was the Alembic and plugging in/ exercising the jacks has fixed the issue.
I am very happy!....
 
Hey, does anyone know what's up with club.alembicguitars.com? All I'm getting from it today is:

Incorrect key file for table './clubalembicguita_AlembicClub/smf_sessions.MYI'; try to repair it

My guess is it was the Alembic and plugging in/ exercising the jacks has fixed the issue.
I am very happy!....
Glad you got it sorted out! I have occasionally had to “exercise” the jacks on my F1 X over the years to cure a similar problem. The folks at Alembic have told me that it’s known issue with the design of that preamp. I have zero understanding of why it’s a problem or why that technique works to cure it, but it does – at least sometimes.

Very cool that method worked for you! I suppose my issue is beyond exercising the jacks. It's also making popping and crackling sounds. Still waiting for Alembic to get back to me.
 
Agreed the first step would be testing the tube or tubes, can't remember if there is more than one.
Your symptoms would definitely point in that direction.

In the old days you could go to any TV store or local hardware store to test tubes.
These days you need to find a local tube amp guy to do it.
This has been super helpful to me as I have a lot of tube amps and preamps (bass and guitar)
