I put these JJ's in my newly acquired Motorola SK14M after restoration.

I don't want to hit the stash of my NOS 6BQ5's.

the bottles are fatter than the standard 6BQ5.

I just can't believe how fat the system sounds now.

I wonder what would happen if I rewired it for four 6BG6 tubes and used a shoulder 5U4 ?

Well, first off, you don't want to use a shoulder 5U4. They are specifically intended for THIN sounding amplifiers. No fat ones.

And, I believe if you go the 6BG6 route, you will start hearing a lot of 15,750Hz whine in all of your audio ;-) not sure if it'll be fat or thin, but it might just be visible :-D

Don't do that!!!

Fat tubes lead to obesity, and we all know that can cause heart attacks.....

Some guys just like to chew the fat and then post pics of their tube stuff. :lol: 8)

I have a Marconi AM/FM with 6BQ6's and a Phat rectifier, but the tone is thin, man.
Needs TLC and alignment. And it needs a big speaker instead of a 6X9.
My Marconi,
She's a boney maroney, she's a low fat raydio. :x

Tubes are original, I think.
