You say the amp's maker said they work? So ask the amp maker wtf they are. There are dozens of equivalent tubes for 6V6, some direct substitutes [eg. 7408, VT-107. plus many 'militarized/ruggedized' variations] by many manufacturers in many countries over the decades [they were first introduced in the mid 1930s]. Many are not exact, but may tolerate higher temperatures and/or plate voltages. Since the ones you showed are unmarked, it would be difficult [read: time consuming] to spec out the size of the glass on all the variants from all the manufacturers. If they work, and they fit, what's the problem? Since you already don't know the mfr, you may never find them again.

My thought exactly. Maple can be very unforgiving.

non-Gibson Les Pauls? I know you mean guitars designed to look like a Les Paul, but not a Gibson [including 'Orvilles and Maestros] or an Epiphone; but by any other manufacturer, it can't be a 'Les Paul'. One of the best 'copies' I have worked on was a Navigator, built by ESP/LTD...great instruments, hard to find, like a Tokai Love Rock [I have never even seen one!]. ESP makes a good variety of LP-style guitars, too. PRS single cuts are great too. But being unfamiliar with the UK marketplace, I hesitate to throw out names that may not be available there. I'd guess Thomann carries plenty of LP-style instruments, and I did suggest a trip to Anderton's [no relation to our former leader] an emporium known to carry Gibson LPs in the UK...

did you check any of the links posted in this thread? I'm guessing not. here,try these: https://www.connguitars.org/ https://jedistar.com/conn/ as to value, check reverb.com and eBay

you're welcome!

with black binding...in the mid 1970s... nope...didn't help....

umm...are you kidding? a pic or three of yours might help, but: https://reverb.com/item/46816831-fernandes-the-revival-57-stratocaster-1957-reissue-mij-electric-guitar-tobacco-burst-1980s https://reverb.com/item/43611065-fernandes-the-revival-stratocaster-57-reissue-electric-guitar-mij-black?bk=

the journey is just as important as the outcome.

" this guy "?

most of them sounded like crap...cheap p-ups and junk pots, wacky necks [the Eko 'nose dive' was notorious]...but you got to look like Paul....

Tubes fell out of favor as solid state took over in radio, television, test equipment, radar, etc. So there were plenty of unused/unsold tubes languishing on shelves.for decades, and there likely still are. That said, from e-Bay? Trust, but verify. the EF86 is a pentode, and does have a very different tone than a 12A[]7, but the EF86 is more prone to microphonics, and how it sounds depends largely on the circuit design [the Dr. Z Rte 66 is a perfect example].

I am actually somewhat familiar with many iterations, [as I would think Isaac42 would be as well] but, unfortunately, there were so many violin bodied basses in the late 60sup tothe early 1980s [I owned two, one an Eko, and another Japanese no-name] and beyond that definitively nailing this down from a fuzzy pic is nearly impossible. It is also possible that that headstock on the bass was refinished white to match the bass. But the head stock does not match Hofner of the era or the Eko: note the big 'scroll' block, and the offset tuners and, although closer to the shape, not the Epiphone version either: so my best guess is a Japanese no-name , although it also does not match with any Matsumoko version I am familiar with, like Univox which was very close to the Hofner's. Not even close to the Vox paddle headstock on their violin... and not a Teisco [Kawai] either [again, more Hofner-y] and not Ibanez [Hofner-y again] There is another headstock a rare 'paddle 3-1' [circa 1967] on the solid body version So good luck...if you get an answer, please enlighten us!

Sherman ...set the Wayback Machine to 1975!

Jim...we are not the Martin repair depot....you should try them at https://www.martinguitar.com/stores You did register your warranty when you purchased it, right? The lifetime warranty has limits, which I'm sure they will explain to you.

we would need a much clearer pic to even begin identifying a knock-off.

again...for what purpose? Any bass amp under 200W isn't going to keep up with a drummer.

leave the guitar out in the sun....and order a dehumidifier for the case.

It will depend on what you are doing with it. Just for home practice? 15W is plenty to hear your instrument. A 30W bass amp is not giggable with a drummer; neither is a 50w, for that matter. If you are working in an acoustic duo/trio, the difference in 30w vs 15W will be noticeable....but speaker size and efficiency come in to play as well.

I never heard of a BB200...is it a BB1200? The 'neck-through' version? That is a very nice bass! Is yours active? The BB bass line kind of died off in the mid 90s, but many notable bassists endorsed the line in the 80s/90s. They are perfectly good basses. Yamaha was comparatively slow getting into basses, but they found their footing with the BB line, as they did with the Pacifica guitars. Some HISTORY...

try here: https://www.souldier.us/# They have straps made out of seat belt material, for example.... Then look at the 'accessories' for their 'strap locks'. https://www.souldier.us/StrapAddOns/products.aspx#

relic-ing?

I'm going to say 'no, it wouldn't'. Are they using the exact same model transformer in both the 'with and without 1/2 power' option? I doubt it.

if the pots are original they should have date codes too. what happened to the s/n on the headstock?

D G D G B D...all 6 I stumbled onto it 50 years ago...still my favorite.
