Thanks @victorludorum , I've bought the glue and filler, so I'll crack on as planned, but I'll keep that in mind for next time - assuming I haven't got any better at carpentry!

victorludorum

It'll be fine. I only used glue as I couldn't be bothered buying any wood filler!

DannyP

I glued it up, routed the edges off and routed some channels for piping this weekend - not very exciting, but progress all the same.

Anyway.... SPEAKER!

My uncle want a Celestion Greenback in there, which seems entirely appropriate.

Looking at used on ebay, there seem to be a lot more 16Ohms flying about than 8Ohms. My immediate instinct was to use an 8Ohm speaker. The finished amp will have 8 and 16Ohm outs.

Is there any disadvantage in using the 16Ohm out and a 16Ohm speaker?

If you have 16 and 8 ohm outputs, I'd go for a 16 ohm speaker in the combo.  It gives you the option of running a 16 ohm extension cab with it (for an 8 ohm load) if you ever need to.  

DannyP

OK thanks, I doubt my uncle will ever need to do this, but worth bearing in mind.

One resistor in the wrong  place

Moved the wrong resistor, but I can't find the 2.2M that should go in it's place, so I'll have to source one.

DannyP

Not quite finished there - a couple of wires still to hook up...

Bit of a Christmas break!

With help from @Modulus-Amps I've got the amp up and running, and the cab is coming on too.

Love this amazing skills too, fair play 

DannyP

V. kind of you @lonestar but skilful, I ain't. The fact that the amp works is more down to Michael Modulus' patience than my expertise - and the carpentry is pretty rough and done mainly with the wrong tools for the job! Filler, paint and tolex will hopefully cover up the deficiencies.

Now, the next amp, mark you - the NEXT amp - well, that will be perfect!

Question for those with more experience:

Shall I buy a 8 or 16Ohm Greenback for it?

I've been testing it with an 8Ohm V30, but I'm building it for a family member who wants a Greenback.

OT has outs for 4, 8 & 16. I doubt it will ever be rehoused or used with an extension cab.

DannyP

OK, no opinions there. 8Ohm ordered.

Modulus_Amps

For combo's I normally go for 16ohm, means if you pair them up later you get 8hms. not that important though.

looking good, where did you get the pine, it looks fairly knot free and unwarped?

DannyP

Just B&Q. I imagine I could have got it cheaper, but they are pretty good about chopping it to size at my local. I tried to pick nice pieces from what they had.
