Throw some jan phillips 12ax7's in there and watch your quad come out of it's coma.

get a couple NOS sylvania/RCA off of ebay and experiment maybe you'll like the russian/chinese stuff better. I have a quad pre I tried everything the only foreign tube that sounded any good was the tungsol but there to unreliable. You can still find jan phillips for a pretty reasonable price, I...

It takes 3 rack spaces just hang in there and watch the bay I paid $500 for mine but I've seen them go for cheaper. I was in the same shoes as you, I was looking for a studio but found a quad for only 100 bucks more. Either way both are great paired with a 50/50.

check out the quad there not that much more,I run mine through a 50/50 plenty of tones mark IIC+ mark III I rarely use the high power switch on my 50/50 low power is real sweet.

I tested two mesa str12ax7 but they were from the early 90's they were actually built in a factory in the old yugoslavia the old EI factory before it was lost in the war, They cost a pretty penny now on ebay the two I had had wonderful gain thick mids real close to the telefunken smooth plates...

I was unable to test my rca 12ax7 black and short plates because they all reside in my 74 twin reverb where there staying!! I'm pretty sure they would have scored a high mark too...regards....J

I have quite an assortment of NOS and newer 12AX7's , so I thought I'd post the results I found. I played through a 1957 custom shop heavy relic, and a 1952 tele reissue with a humbucker in the neck ala keith style. So mind you , my final choices may not work for you if you are using a les paul...

how firm are you on the price there, I'm out in cali?

I just bought a 50/50 and I'm using a BAD CAT X-TREME pedal as a pre into channel A>2X12 and it's extremely loud. I can't even imagine how loud a 2/90 would be.

Thank you very much for your quick reply Gonna change the PI's to NOS Telefunkens.

Hi I want to change the preamp tubes but am unsure as to which tube belongs to which channel. The amp is an older 50/50 built in 1989 thanks in advance for your replys.....J

Love my heartbreaker will never let it go, reverb sucks but thats why I have a 74 twin. I modded channel 2 to marshall specs but ended up going back to original specs, just use the tone controls.

looks like there hand wired though mesa can't compete with that

I have my heartbreaker loaded with tele's, bugleboys and mullard's sounds so much better than the mesa tubes that were in it before
