the amp had a slight tube rattle, i contacted sweetwater and they sent me a new set of 6v6 tubes.i had narrowed the ratttle to one of the
GT 6v6gt and they sent me some EH 6v6GTs. i installed these tubes using a bias probe.
initially the bias read 31 for each tube.
the Vp read 390, using the weber calculator, said to bias these at 24.5 mv
with 9 watts dissipation.
i installed these tubes thinking, well removing the rattle, ill keep these tubes until i get my hands on some TADs 6v6.
To my surprise :shock: , the tubes rounded the harsh highs tightened the bass, and increased headroom.
i couldnt believe my ears, sounded really good, so i removed them and installed the GTs, nope, sounded better using the EHs, the amp sounded harshly bright with GTs.
are the EHs great tubes or are they hit or miss?

Great tubes! And, tough as nails, nice score. IMO, EH are some of the best sounding, and most rugged new production tubes that you can get, and the price is sweet too. EH, Tung Sol, Sovteks, and others all come from the same Russian factory. Big fan of the Reflector factory! GT also use some of these tubes.

+1

I've used the EH 6L6's personally and installed EH 6V6's into a number of clients' amps (both PR and DR, vintage and re-issue). They're study, cost-effective, and provide great tone. They're a win-win-win IMO.

Thanks shim,
I had read somewhere else, can't remember which forum,
but other tubes were reviewed however current production
He thought the EH were really good for the price .
TADs are still in my sight for power tubes but I'll wait till
These tubes are done.
Which brings me to my next objective,
Now I'm on the fence with replacing the speaker with a cannibis Rex
Or a weber 12f150

The Weber is less efficient and better suited to vintage tones (think "Jensen C12N"). OTOH, the Emi CR provides a more modern vibe and has a higher SPL (similar but not quite identical to a V30 or a Greenback). Either speaker would be an excellent choice based on the type of music you play.

Thanks arjay,
Jensen c12n (vintage) sounds nothing like
The c12n in current production I gather.
I have that speaker in the Bjr nos and
plugged it in to the drri for shizt and giggles.
it sounded overly bright, bottom end was
Meh. But the p12q sounded really nice in the Bjr .
I think the weber 12f150 50 watt light dope is
the way to go.

They really don't IMO. I have vintage Jensens in a couple of amps and they really sound smooth and punchy, albeit a skosh "quieter" since their SPL is relatively low. I recently acquired a Fender-marked C12N which I'm going to field-test soon in my '68 Deluxe Reverb (a JBL D120F is currently installed). I think Weber's 12F150 will be a very close stand-in to a vintage Jensen once it's fully broken-in. Rebelsoul swears by them.

Let me know what you think about the current production
C12N with your trial run.

It's not a contemporary re-issue Jensen from Italy -- it's a made-in-Chicago Fender-marked C12N from 1966.

Sorry for the confusion.

Not to hi-jack the topic but what are your opinions on the Vintage30 Arjay, in a DRRI?

The V30 is a fine speaker. However, it never really sounded "Fender-y" to me in the traditional sense. It's more of a modern pork-rind-and-fatback tone. IOW, it's at its best when used in quartets as per the classic 4 x 12 sealed-back cab configuration. That said, it's still a good compromise for someone with a single amp who needs to cover a lot of sonic ground -- ie: a classic-rock cover band where the fare might transcend such a diverse array of artists as Tom Petty, Angus Young, and Ted Nugent. You could do a lot worse than a V30, especially the older Ipswich-made editions. For truly authentic no-excuses Fender vibe though, I'd go with a Vintage Jensen, a Weber, or a hemp-cone Tone Tubby.

Thank you Sir!

Funny you mention the 4x setup as that is typically how I've seen them...always in a 4x speaker cab.

They do well in pairs too, as with this '66 Bandmaster "utility rig" I built a few years back......

Image

And lest this thread drift totally off-topic, I've had a pair of EHX 6L6GC's in this amp for nearly two years now. Thus far, they've performed admirably with no reportable discrepancies. I have them biased at 34.5 mA, about 65% of max plate dissipation.

You sure know how to make a guy happy. :wink:

I have a quad of EH6L6 in my X100B, and they sound terrific, TR-like cleans and very Marshally sound when driven.

And this little beauty (not mine, but my work) has a pair of EH6V6 idling at just under 14 watts, it has been used professionally almost daily for about a year now.
