Retubing My Marshall - What NOS Tubes Work For You

HI !

Aside from Mullard & Brimar - obvious choices - what are you rolling these days ? Any NOS U.S. tubes get " the tone ". I'm looking for '60's & '70's tone - no metal. Need EL 34's & 12ax7 ideas. THX!

Which marshall? What are you going for?

Leaving the previously mentioned "obvious choices" out doesn't give us much to talk about. :hide2

I tend to go for low to mid gain and pref a creamy harmonics versus something bright and stiff. On the pre-amp side. I still dig Tele smooth plates in the PI in many cases. I have some GEs 12ax7s that I will try out some times. If the amp is dark I'll add in an amperex, and I think I'm also running one of these in the PI right now in my Bass 35. Other than that, I primarily stick with a Blackburn Mullard in v1 always.

RFT is darker and breaks up sooner than Brimar or Mullard. Telefunken or Amperex are a bit brighter and bit cleaner, and a bit cheaper. ANOS tubes are a better way to go than NOS IMHO, as long as you're getting them from someone reliable. I think that some folks like Sylvania for those amps as well.

Power tubes-Siemens are less expensive than Mullard, although not cheap any more

Thanks. I've got some RFT 12ax7. I need a third. What matches up well with them in your opinion ?

So... power tubes are always a second priority for me a mostly about longevity. Pre amp tubes for amps... RCA and GE seem right to me in fenders. Amperex / bugle boys sound right in British amps like Marshalls.

I've found the first tube most important. Definitely put an RFT there. Second tube less critical, needs to be a decent tube. Last tube overdrives when the power tubes start to cook, so an RFT there as well, IMHO.

a Sovtek LPS will sound remarkably good in the PI position, if you can't afford a vintage Telefunken (etc) long plate.
an RFT would be my least likely choice for PI, the only thing worse would be a JJ ECC83S. o_O
in V1 & V2, RFTs are superb for those 80s hair metal tones in a 220x ! :aok
I still go with Philips made i6x ECC83s or Tungsrams for Plexi style amps & 220x, occasionaly a Telefunken smooth plate or EI for PI.
power tubes are XF or anything RFT made (dimple tops), for semi-NOS I also dig true =C= .


I'm referencing the manufacturers here, branding is irrelevant. :dunno
there is no law, but in general I tend to prefer US tubes in Fender derived circuits, and European in Marshall, Vox etc types.
with Boogies, D-styles, Soldanos etc you just have to experiment to find the magic recipe, for me it's usually US style power tubes (Sylvania, TAD) and a mix of various preamp tubes, individually selected for that particular amp.

ymmv,
Rhino
