just realised i cant do 16 ohms as i thought originally, just 4 and 8.  its a shame because that guv'nor was drawing me in

anyway... i think i have something good sorted... more details once i have it all sorted

cheers guys

The peaveys are also 16 ohms, Wez. In other news, G12K-100s only come in the 8 ohm flavour (unless you get an Orange 1x12 cab, for some bizarre reason!)...

Looks like Wez can't use 16 ohms - so I will still have the Eminence and the Peavey in the loft!

thanks for the kind offers Mike and Roo, i was going from memory when i said i could use 4, 8 or 16 ohms but when i actually dug out the kit instructions it seems i cant do 16 afterall.

anyway, HTH put me onto something that i am looking forward to trying... supplied by our very own Jpfamps

more details and a review once i have it sorted

Could you not solder a resister in to change the load?

havnt got a clue... amps are not my speciality at all - but i do know from the instructions that i can swap a wire for either 4 or 8 ohm operation

Hmmm... The plot thickens...

Presumably the cab is *already* loaded with a resistor on one of the connections to allow either 4 or 8 ohm operation (given that it's a 1 x 12" cab, and the speaker only has one impedance value!). Worth opening up to check. In principle, I'd imagine you could switch out the resistor that's currently there to allow either 8 or 16 ohm operation...

no roo, it the speaker out on the amp kit i made.  The output transformer can be hooked up for 4 or 8 ohm operation. 

Currently its wired for 4 ohm operation buti can change the amp output to 8 ohm by swapping a wire.  then i can get a single 8 ohm speaker that will also work fine with my little rock as well (i plan on having jack connections between speaker and kit amp so i can still unplug the speaker completely and use it as a 1x12 speaker cab for the little rock)

So one amp that can be 4 or 8 Ohms (champ kit)
One that can be 8 or 16 ohms (little rock)
a 2x12 cab that can be 4 or 16 ohms (the current one)
and hopefully a new speaker in an old 1x12 combo which will be 8 ohms


its all clear in my head

tbh the only reason for all of this is that i like the look of trace elliot velocette amps and happened to bid on the empty shell of one

Not mine, but the look i like:
http://www.chambonino.com/work/work12a.jpg

the one i am getting is black rather than green but thats ok as i would feel bad recovering a sexy green one with red tolex... since its boring black i will probably recover it red and replace the grill cloth with a biscuit one - especially since i have some left over from doing the 2x12

the positive side is that it means i will finally have a aesthetically pleasing home for the amp kit and i hope having a 1x12 cab will let me push both the amps a bit harder than i currently can.   the downside is that it might make my 2x12 redundant - but i really like it.   

it may be that i end up using one of the old speakers from the 2x12 in this new housing and eventually get rid of the 2x12 cab - before that i want to try out a new speaker or two in order to make sure thats the best option for me

the cabinet finally turned up earlier this week so i have recovered it in red and changed teh grill ready for the new speaker thats now ordered


this is my second time tolexing an amp.  first time i used contact adhesive - this time i used pva.  i think i prefer contact adhesive but i actually got better results this time because i prepped this ply cabinet better than the old battered chipboard one i did last time.

the old tolex came of very cleanly so i used it as a template for cutting the new stuff - i didnt bother with teh sides as i quite like the look of red and black

nice job Wez, hope you like the speaker.  I'm waiting for a set of OLD Goodmans alnico 12s to come back from Tayden - getting reconed and the power handling bumped up to 30w a piece, perfect for an AC30.

which speaker did you go for?

its the M-series, thx for putting me onto it.  I am getting something that should theoretically  be somewhere between a chinese greenback and a heritage greenback for less than the chinese one... i will let you all know how it fares once i have it installed - and then i suppose i really need to spend some time playing to break it in


i should point out this is the first new speaker i have had since i was 17. back then i got a 1978 voxac30ss with greenbacks and since then i have been using a 70's carlsboro cab with mckensie speakers which seem to be re-badged greenbacks... so i am aware i may need to break the speaker in before giving too many judgements

break-in of speakers is definately noticeable - I think you need to give them a month of serious volume before they settle down.

depending on the speaker, there is always one frequency range that dominates - my Creamback G12H-30s (55Hz bass cone) sounded REALLY thick and bassy when I first got them reconed, but the top end really opened up after a while.  The G12H-30 (anniversary series) with 75Hz lead cones sounded really midrange-heavy at first, then settled down too, but probably had just a little bit too much top end for me (hence I use 55Hz bass cone versions now)

they sound like a good thing james but dont suit my requirements
