Hi. I just received a 1968 Silverface Twin Reverb amp.
Are the 1968 models naturally circuited to be blackfaced,
or should it be modified.

Also, are there referenced to comparisons of an amps' sound
before and after the blackface modification?
Obviously, many Silverface amp owners do make the modification,
but do all 100% like the mod? Any complaints?
Thanks for your responses. Toppscore.

Mine was a 1968. If the amp is in good working order there is no really good reason to mod it. The mods necessary to blackface are very easy and quick to do, but not really necessary. I believe it's the AA270 but YMMV. As for the sound, it sounds great stock. It's literally as close as you get to a blackface with a factory silver faceplate. The only really worthy BF mods to that amp are to the BIAS circuit, making it easier to tweak the bias to your liking.

It's a 1968, the faceplate is a RI replacement part from the 90s. My friend owned a dealership. The cabinet, chassis, reverb tank, and transformers are original. The rest is new. The speakers are some old EVM12Ls (early 80s I think) that I sent to EV to re-cone about 14 or so years ago and have been in the shipping boxes ever since. I used to use these for my PA systems, so these were spares. The internals are all new CTS pots from Mojotone, orange drops, and a mixture of metal oxide and carbon resisters built on turret boards. Most of the circuit is stock AB763. The tremolo is bias controlled instead of the bug. It gives a smoother sound, no clicking. Currently the normal channel is normal, but has the Trem since it's bias-vari. I'd like to either make it a switchable gain stage between the VIB channel and the PI, or at least add verb to the normal channel and change some values, perhaps to the tweed era. I haven't decided yet. Really enjoying the amp as is. Leaning toward the gain stage cascading idea (dumble?) just because I can't seem to find a distortion pedal I like. Alternatively I might build a DR and just crank it up for my dirty channel.

Here is my 1969 Twin Reverb. It has the wrong grill cloth, no trim, no foot switch, and still has the 2 prong plug. Even so, it sounds amazing! I am looking to sell it (or trade it) so I can get something smaller, since I don't really play outside of my house anymore. My question to you all is: Do you think I would make a profit if I put money into the cosmetics, or should I just sell it as-is? I'm not using this forum as ad space, just wondering what condition is best for selling. Your input will be very helpful!

I posted earlier that I got a 1992 TRRI for $375 at an auction. Well, I removed the chassis and It's PTP wired and Blacfaced to AB763. Right down to the Fender Tag board. No PCB. It has a half power switch too.

I have and I put a very long explanation of it earlier in the thread (duh).
As said, it doesn't change it enough. If you do that, and switch the speaker to a much lower sensitivity, then you might be closer. Some kind of power soak will take your even further. I am contemplating several possibilities as I can't play it past about 3 now and it sounds really amazing at 7-10.

I also tried it with the speakers in series at 16 ohms and used a pair of 6V6s. That's cuts it further but it's still not quiet enough.

My speakers are EVs which are VERY sensitive (loud).

Would a master volume work? In the post above is what I have. Most of the time I can't play it past 3 also.

I recently got a twin head cabinet from Mojotone, and I had an old Fender speaker 2x12 cabinet. So I split my twin in two.

Each half weighs appx 43 lbs now. So much more portable. Love the Twin! Best amp in the world IMO.


:p take care...

I finally get to join!

I've been playing through a blackface Twin (serviced by NYC's legendary Blackie Pagano) at my weekly gig in New York City, and I fell in love with that amp. I've been looking to buy one for along time, and this week I decided to pull the trigger.

A friend of my bass player has been trying to sell me this amp for nearly a year. I decided to go for it, and a fistful of cash and an '03 Gibson SG Special got it done.

A 70-something Silverface Twin with orange basket JBLs.

Needless to say, I am thrilled. This is my first Twin, and it's a good one.

Nice to be here, finally. :D

I'm joining the club by way of a 40th Anniversary FSR ('65 TRRI) I picked up through TGP. I was a Vox AC15 C1 club member for a while, but found too much overlap with my other 12AX7/EL84 amp, a Jet City JCA22H. A friend brought over his new (to him) '71 SF TR and boom, the Vox traded places with the TRRI.

Also featured is my '86/'87 MIJ '62 Custom, which has been having lots of good 'clean' fun with the blonde...

Had an AC30 I bought new earlier this year for sale... Accidentally swapped it for a 1979 twin and an Epiphone dot with a hard case.
Who could say no to that?

Had it checked over by an amp tech, $50 later it sounds like a brand new amp.

Here's the rig - Guitar in picture is a 2010 flying v with DiMarzio air classics.

Welcome to the club Audio! You "accidentally" traded a vox for a twin? Good work! Nothing beats a twin reverb, nothing! Congrats again...

Yeah, I was looking for an outright sale on the AC30. I only hit the then-owner of the twin up thinking it'd either be too loud or too clean and I could sell it off for a bit more after cash difference my way.

Oops.

The dot has since gone and I'm selling some other stuff instead. Have got myself a nice Les Paul to play through it when I'm not playing the V; should be getting my tele back from the doctors soon too.

I still have my blue tolex AC30 because it's the man, but the twin's pretty much where it's at for me now.

TL;DR:
Ended up loving it and decided to keep it. :D

No pics but I just last night picked up a '72-'73 SFTR. Very clean. 25W Greenbacks installed. Sounds Great!!

I've had a '66 and reissue prior.

I agree. Best All-Around amp ever.

Don't really care how heavy they are. That's what casters are for.

Thank you Big Bend.
It does sound great. Due to its age, size, power, etc. I've tried for years to find another amp I could use regularly and retire the Twin but no amp I've tried (and I've tried many) has been able to give me the beautiful, pure tone I get from this amp.

once you go twin, you never want to go back.....i can't even lift mine anymore, even though it's in a separate head and speaker configuration, but nothing else comes close to the sound and feel....

Hey y'all. I would greatly appreciate some advice/opinions. I have a chance to buy a mid '70's black vinyl/silver-face twin reverb.
The guy that has it is a tube amp collector and seemed pretty straight up on the phone.
He said it has some normal wear, and it's in the shop right now being repaired because he said even with the tremolo turned off it would still make a popping/pulsing sound.
Also the in/out volume boost, (or whatever it's called, I'm not that familiar with these amps), switch does not work, it's stuck on "normal", the boost does not work. He said other than that it is a clean and quiet amp, and should be out of the shop this week.
My question is, is $550.00 a good price for it? Thanks!
