Where do you guys buy replacement tubes?


I'm sure it's been covered, but I haven't found it. I'm looking to replace my sons tubes in his amp. We have had some bad experiences to date with suppliers and I would like your recommendations on good suppliers. His amp uses 6336A tubes, a real odd ball, so the supplier needs to cover alot of types I would guess. Thanks for your help, J.D.

No need to worry about it being to busy if there is something you need...that's not where it's at.

The delays are not happening much anymore except for odd stuff. The things we do every day go out the door pretty quick.

I just made an agreement to have the best talent in the industry custom make a new tube burn in rack and matching fully regulated test rig.

What we have now is good, but we actually use power amps to do burn in before matching, and sometimes the amps blow up (better mine than a customers)and I have to perform surgery to fix them. Then we use a pre-heat rack before testing the tubes one at a time. The new rigs will burn in 20 at the same time, then the test rig will have 20 at a time getting up to operating temp while one is being tested. Super cool.
Kevin, what do you mean "the amp blows up"? I'm wondering if that isn't what happened to my sons amp. What would I look for? Thanks, J.D.
"the amp blows up":tech jargon for "it broke down", which could be anything (blown resistor, capacitor) and might be
something simple or serious. It's really not possible to
try and diagnose stuff online without more details than you
are giving (and possibly some details you might not be able
to give without some experience working on tube amps).

BTW, you can buy brand spanking new (they still make them)
Cetron 6336A or 6336B from Richardson Electronics, but they're not cheap...$141.00 list. A better idea for this
tube type (or other weird industrial tubes) is try
Fair Radio, www.fairradio.com , they've got new 6336B's listed for $30 each, which is a heck of a deal.
Yes, you can replace 6336A with 6336B.

Oh, yeah, Kev, you might talk to your Fedex rep, I don't
know if they can do it where you are at, but we managed
to get our Fedex Express pickup pushed back to 7PM, which saves a lot of last-minute hustling...if you ship enough
Fedex Express they ought to be giving you a discount, too.

Uncle Ned
here the last pickup I can grind them for is 4PM. We are at the top of the street right below the entrance to Mt. Baldy. I know they pick up at the larger drop off points near Ontario Airport by 5PM.....

Don't forget we lose a couple hours on you Ned. My driver was late yesterday, here at 6PM...and here it is 6:53AM in California, and the package will be delivered on some island in Florida within a half hour. I don't know how they do it.

I don't know if I really believe Richardson is making 6336A or B....not that they would ever ever mis-represent ANYTHING...what with the great job they did re-releasing the Amperex Bugle Boy using the original burn in racks from Holland and all.
