mix and match pairs? Not sure what you mean?

It will work just fine. Those are re-branded most likely Mullard made tubes. Sylvania never made tubes in England. Either way they should be really good tubes. Do realize the 299B is not a plug and play amplifier when it comes to the output tubes they do require proper biasing when installed and periodically after that.

I wish she would have just banned you

Neal got it thanks I also got an email. Not sure why I can't get the forum to send me thread notices. See you in the couple weeks!

So August 10th is the final date? For some reason I'm getting no notices from the forum software... so if someone could update me of changes via email if you think of it that would be great. My life is a whirl wind so I just never log in here as much as I used too. I do plan to come to this get together. email craigATnosvalvesDOTcom I'll also need the address. Thanks Craig

Hmmm the area he sings about in the song is right where I live now and grew up... he's still seen hanging in the bars around here now and then. The area really hasn't changed all that much wish I could say the same thing about southeast Michigan!@

As long as I have some notice I can usually make a day or two get away happen. This sounds like fun! Wish I had a way to turn on notices for just one thread... heck maybe there is. I'll have a 3 hour drive to get down there.... I found the button for notifications. Not sure what it will notify me of...

Funny thing is NO TEST EXIST that the answer comes back to confirm NOS or a truly measured and accurate life test. A tube tests the same for 90% of its life and than drops like falling off a cliff.

Buy those vintage 7189A tubes if you can confirm they are truly NOS the N stands for New. I say this because the definition of NOS has been abused to include used tubes for years. Yeah the 299B is a 7189 amp it can use the 7189A just fine.

Eric.....No amount of thinking or design are going to make $300 in materials worth $3700....not in my opinion. I do believe I have a right to my opinion.....

The work looks to be nicely done. The brown faced LK72 with a nice face plate fetch pretty good money so I say even $950 isn't a bad deal if you can audition to confirm proper operation.

Nope the LK72 is indeed the kit version of the 299C the LK72B is the kit version of the 299D
