Yeah it’s a lot better hobby when you’re young, dumb, and full of, well, money

At one point, I could have an engine out of a Camaro in an hour. We had 4 racecars, and I pulled 13 engines in 4 months

It takes me awhile nowadays

“young, dumb, and full of, well, money” …no truer words for a car lover or musician!
 
humbled by the vote of confidence Ring..
truth is, those stickers are the wrong ones to use for 12AX7s since Gm pertains to pentodes and not triodes (12AX7s are twin triodes hence the dual set of values) whose gain is specified in Amplification Factor or u (MU). this value specifies how many volts the output will change as a function of the variance of the input voltage (dV/dV). in a 12AX7 triode it’s usually about 100 meaning a 1 volt fluctuation at the input will result in a 100 volt swing at the output. Transconductance (Gm) on the other hand is used in amplifying tubes (usually power) with 4 or 5 (instead of 3 as in triodes) electrodes denoting a swing in current (instead of voltage) at the output as a result of an input voltage fluctuation (dI/dV). the folks at TC may have run out of stickers, who knows….
iP just means the plate current in each tube when the gain measurements were made by the tester as u and Gm are very dependent on this current (mA in this case) value.
this said, I would start with one of the mullards at the phase splitter location of the tube amp (since they are identical, hence well balanced for a splitter) and the Amperex at the gain stage. don’t really know the topology of the class D amp but these placement choices aren’t as critical in them since they don’t operate in a push-pull configuration…..
hope this is not too verbose, PM (or call) me if you want….alternatively, you can come over and we can verify those values with my Orange tester and do some tube rolling…

Well said!
 
I used to love football. Then the greedy owners let the greedy Spanos family leave San Diego. I haven’t watched a single game since. I won’t be watching tomorrow.
Superbowl is a fave time to hit one of our favorite restaurants. Usually busy, during Superbowl it’s pretty empty because everyone is watching somewhere else - that has a large screen tv.
 
I’m no expert. But I know in the Mesa Subway 800 series heads it makes a difference. The WD800 takes the Chinese made 12AX7. The TT800 takes the Russian 12AX7s if you want the preamps to sound as the designer intended. I would ask the folks at Orange what they recommend re Millards in those heads.
It’s tubes. You can try it all 4 ways! But I have found only one amp Mullards didn’t make better. It was garbage. Don’t recall what it was.
 
Forgot* to post last night(Friday,2/9): gig at semi-local Elks Club. Used the Epi Embassy 'cos we've played there B4 and I know that the 67NR's neck will overhang the dance floor by ~1.5 feet based on my position to the drummer's left. Two more gigs-w/ 2 different bands-this coming weekend. Should be able to use the 67NR for both(Yay!)[might hafta use the Embassy for Friday's gig-I'll take both, leave one in the gigmobile].

* OK, I was too effing tired:sleep:

We were supposed to play as a trio this morning but the second vocalist / percussionist got sick, so it was just the leader/vocalist/acoustic guitarist and me. It was a blast. I used more variation in the pedals than usual.
 
Anyone here rock an 8 string?

I played in a 3 piece band in the 80’s and the Hamer 8 string can really fill in as a rhythm guitar by playing bass chords with bass lines that have piano like tones.
I can only play a song or two now but back then I could play 3 sets!
I don’t like that race stripe but if I could find one I might pull the trigger.
Four is my number,
My number is four.
Offer me more and
I’ll show you the door!

(Not really.)
 
Thanks you guys for all the Chime-ins, after seeing the reply from @TBird1958 I was sold on there no-sale. More all these confirmations (and @Engle ) I'm done for sure.
I probably just need to chill ... And I played the CP last night at a gig and there's nothing wrong with that bass. Between my two regular players I've really got everything covered.
Should practice what I like to preach...
That’s how I feel - between the Grecos and CP, I have things covered.
 
White Wednesday!



been messing with pickup changes in some lesser liked treble geetars, I’ll be tackling some base geetars next, but that will mostly involve purging my last set of jazzy pickups.
Do you have time to actually play all those string things? Or just to mod things?

I actually play treble geetar more than base geetar…

I consider myself a singer.

I learned treble geetar so I could accompany myself and not worry about geetaristras flaking on me.

I started seriously playing base geetar 5-7 years ago because of projects or just jams held up for the lack of competent base geetarristras.

my 11 year old is taking drum lessons so I don’t have to.
 
Why is that?

Here’s one good description.
Or at least the graphic tells part of the story.

When I was in high school, if you were seen driving a 4-door sedan it was yer parent's car. 2-doors only.
In those days we were 4 door only although a (very) few coupes and station wagons came in as fully built up imports. Some in RHD, others in LHD and converted here by GMH or by one of the converters (bit of a small industry). Mostly imported by dealers I think, sometimes GMH themselves. Generally V8s. We eventually got local assembled V8s, 283’s for a couple of years but 327’s in the later 65/6 - 70/1 years though 68 was the last body we assembled.

Found this the other day, an ad for the ‘31’s. The second ad was a GMH dealer in Sydney that used to directly import new cars from GM and had a conversion facility (or contracted to one). Interestingly (to me anyway) is that the (factory backed) conversions have restarted since the local industry shut down in 2017. But now they call it “remanufacturing”. The outside conversion companies have continued as well and do the stuff that the factory doesn’t bring in. A top line Sierra instead of a Chev, or the bigger F trucks.

"Remanufacturing". Right. And "garbage men" are now "sanitation engineers".
