I bought back a 406 off Damö. I’d originally swapped it with him for my first 408 (left hand cab) and 220 amp. Since then I’d restored a 406 narrow and realised I really wanted another 406 so jumped on this when it became available.

Here’s my ACC Acoustic rig. The 301 cab I bought new in 1973 w/cover.  I was in the 11th grade.  The 370 head I got a couple of years ago.  It a terrible brown tolex recover.  I re-did it with Duratex. I had the catalog pic on my bedroom wall as a teen...amp porn.

Had to do some re-organising in the basement so it was a good opportunity to show off my Acoustic 136 combo.

The combo was purchased new in 1971 from Roger Jenkins Sound Centre in Cardiff. Roger was one of the importers and distributors of Acoustic products at the time and as an employee I enjoyed a small staff discount. The Combo is all original except the original Eminence 100w 8 Ohm 15 ins square magnet speaker has been replaced with an Eminence 400w 4 Ohm  Kappa -C 15ins. (I still have the original speaker). Back in the early 70's I was not knowledgeable enough to calculate whether the Kappa-C had the correct specs for the folded horn reflex cab design, I just thought " well it's Eminence, it's 15 ins and it can handle 400w , so it must be right". Fortunately it has worked and lowering the impedance from 8 ohm to 4 ohm allowed the amp to output it's full potential.

The castors and the H & H bar handles were added to help with handling. It works really well and sounds awesome. Isn't it strange how we used to manage our sound tailoring with 3 simple controls? Volume, Treble and Bass plus a Bright switch to and a little sparkle. These were fine amps built in California with great pride and professionalism. It's really sad how big corporations buy up innovative successful companies only to loose the key personnel and run the businesses into the ground. We are fortunate that those clever engineers and Innovators moved on to create other new enterprises that we bassists have benefited from.

This combo replaced my Selmer Treble'n Bass 50 Mk2 and Selmer 100w 1x18 Goliath rig. I still have the T'nB 50 Mk2 amp and I plan ( One day) to rebuild it with all new replacement transformers, valves and caps. I'm sure it will sound fantastic thro one of my Barefaced Super Compacts.

I’ve managed to get hold of a 361 rig. It’s in great nick for a 53 year old amp. A little dusty and grubby rather than damaged. I’ve given it one clean but it needs a going over with a nail brush I think. It also had the top grill missing so I’m in the process of making one. Just need to bend the aluminium frame.

Great thread this, some lovely Acoustics 🙂

Been having some fun recently with this, as the neighbour's away on holiday 😁

I understand it's from 1980.... Big sound using a blend of both channels A & B at the same time

reposted from another thred....

sorry if anything below has already been said above.

Here is mine, a 136 1x15 combo

50 year old in september, cool as hell and quite rare in the uk i thought till i seen some on here , you dont see many though about.

iv been doing this up for a while now, amp is working fine,  i have taken the back covering off as it has shrank a fair bit so have to get that back on, anyone know where to get the tolex cloth ?

i have a new set of 4 wheels to go on 2 of them lockable as the old ones were f%&k%d.. and some new corners,   it has the very hard to get original speaker in it,  a White Altec 421-8H, H meaning it has the upgraded copper coil fitted which also works great i have seen these these going for nearly as much as what  the combos worth by its self ! ! ( or was this the original speaker ? )

, the amp is a great design,  for example, to change the power transistors these are just screwed to the side and can be pulled out by just unscrewing to two screws, no soldering at all, made for quick changing in the field,  its shown here with the speaker out, but will put it back in and get a better pic.

 

Well here is a manual for the 136 with aservice manual as well , very handy as the same amp design went into a few of the range.

https://www.manualslib.com/manual/1039548/Acoustic-136.html

 

and some upgrade info, says basicly that 2n3055 trannys can be used ?

"cd_david

The tolex, grill cloth and corners are just the same as fender early 70s. I’ve recovered and regrilled quite a few. I usually get it from SolSound in Watford. 
Thanks"

 

Thanks for that dave, i will look into that. :drinks:

HUMMING Earth Hum ?

if you are getting any humming as mine was, first of take out all the sockets and pots and scratch behind to give everything a good grounding, that should be first port of call to cure it, sorted mine out anyway ...see last pic.

and some amp pics ya might find helpfull.374221064_ACC150PowerAmp17-12.jpg.879720a34b55931a9da1854350246475.jpg

sad indeed, a sign of the "more to do with profet" times, regarding your selmer, years ago i was in a organ based groove band, sugarman 3, jtq, rubin wilson, johnny guitar watson type stuff, the key player had then a selmer leslie till he could get a hammond one, when he did, he gave the selmer to me as the cab by then was just Fu@k&d, so i chopped that to bits to get the same 2 chan selmer valve amp out and the goodmans 15" speaker, i housed the amp in something i built like a fender bassman 135 surround, and the speaker in a matching cab, i then used that for years in a blues groove band, as it had just the right sound, untill i turned it up and the back of the speaker cab would rattle ! (too shallow bad design on my part) but it did a great job for that sound. nice amp that Selmer Treble'n Bass, it was better than my musicman 75 valve bass head i had at the time i thought.

How could I have missed this topic? Here's the 118 combo I bought for €50at a thrift shop here in Amsterdam. It's currently getting recapped. It's insanely heavy but I like it A LOT.

Nice, I reposted your picture.  It didn’t work for me.
