Hello people!!
I just converted a 1969 Webster mono PA amp to guitar.
6ac4, 6au6, EF86, 12ax7, and two 6V6 tubes....all original RCA.
I do not want to subject the beautiful sounding RCA 6V6 tubes to a road trip.
Could someone please recommend a rugged & dependable 6V6 tube that won't blow up during a bad cover of "Pretty Woman?"
THANKS!!
Steve
Follow Ups:
I want to thank everyone who gave suggestions on 6V6 tube choices.
I went with the Tung Sol....even though they cost more than EH, JJ, Sovtek, etc.
Too many people I respect (Jim McShane, Mike at KCA, and others) have suggested the Tung Sol 6V6GT tubes.
Again....thank you all!!
Steve
I agree, I have a couple of amps with 6V6GT tubes. I have a pair of RCA grey glass in one Deluxe, Raytheon grey 6V6GTY's in a Princeton, and a Champ with Sylvania 6V6GT; all NOS and all in the amps for years.
They've been hauled about and not babied. They all sound good. Nvr had any power tube problems.
I've had such good luck with these old tubes, that I've nvr really tried any new production models. I've replace some other ppl's amps with NOS, upon request. These folks all seem to be satisfied.
GE 6V6GTA are tough tubes. I seen these with 375 volts plate take abuse year after year in a guitar amp. Sound a little on the clean side though.
Most of the early manufactured tubes were the best manufacturer's effort, with the finest materials and quality inside. If you have the room for them, 6V6Gs are wonderful sounding. However, finding unused matched pairs or quads is like finding unobtainium. Metal 6V6s are very underrated, and extremely inexpensive. Just leave a leather glove near the amp, if you have to change them, quickly(LOL).
The JAN type tubes were made for military use; failures were not an option. There were some brown based, micanol, 6V6GTYs that are very worthwhile, at a price though.
Stage requirements may upstage sonic desires. Guitar and ex-PA amps tend to have higher voltages than hifi designed stuff. If your B+ for the 6V6s is over 325V, I would want to be able to view the inside of the tube, to see if the heavy blue glow, or red plate syndrom, exists, warning of impending failure. So, the dark glass or metal tubes, while sonically excellent, might hinder your flat-out wailing.
On the other hand, if your rebuilt amp is stable and cool running, you must try the metal tubes and early dark glass versions, as their tone might be just what the doctor ordered. During the break-in period, making sure the amp is stable for long hours and runs cool, you might want to source the military grade JAN types. Rock On....
They are more rugged than American 6V6 varieties and are actually equivalent to 7408, a beefed-up version of 6V6.
I have some black glass ones from the mid 50's, sound great.

The all time most rugged 6V6 tube is the Bendix 5992 which is a drop in for 6V6. Only problem is they are rarer than hen's teeth and pricey to boot.

While the JJ 6V6s are "rugged" (assuming JJ built them right, they don't often do well with octals...) many say they sound more like 6L6s. The tube of choice is the Tung-Sol reissue 6V6GT. It's VERY good, affordable, and available (although in short supply as the demand consistently seems to outstrip supply!).
If your favorite vendor is out of stock drop me a note and I can help.
Whut he sez. They sound terriffic for hi-fi, too. Better than 99% of the hallowed NOS brands.
Aloha,
Poinz
The current production JJ 6V6S are very rugged tubes...and they sound great to boot.
As a gigster that has used a vintage Paul Pine 605 (a single ended 3-5 watt single 6V6 amp), I would ALWAYS have a spare or two in the gig bag for just such emergencies.
NEVER leave home without the essentials- EXTRA tubes!!! My Spares include a few vintage GE NOS.
(how I USED a 3-5 watt amp as a Bass Player is another story!!!)...

A SE 6V6 for Bass? Please continue . . .
Simple for me at least- a foot switch selector between the bass and two amps, my current clean rig, and volume pedal to the 6V6 amp. The amp was always run with the volume on full. I used the volume pedal to control the overall level to the 6V6- at full on, the amp had a wicked distortion, that when combined with the clean rig, made for one mighty rock and roll tone.
The 6V6 amp now sports a pair of Eminence Legend 125 12" speakers and gets a new power tube every once in a while (they don't like to be driven full out for very long!)...
