I have to admit I did like the drum kit - or lack of!!

Only if you want to destroy a perfectly good 15! A 15 can pair with a 2x10 reasonably well but anything else puts the 15 at serious risk of failure.

I changed all the speaker connectors I own over to SpeakOns many years ago. 1/4" Phone jacks are an accident waiting to happen IMHO.

Really the manual is as clear as mud. I have the feeling that the combo has a 4Ω minimum which is filled by the internal speaker. Then again the manual says 'short circuit proof power amp' so who knows. I would be very wary about connecting a speaker in parallel with the internal diver. That would mean a 2Ω load. Get it wrong and you have a blown amplifier. Incidentally most combo amplifiers develop their maximum power into the internal speaker.

So OP did this solve your problem??

Earl Preston's Reflections. I left the band late 1968 due to having to work outside the city. Met my wife in that band an June 06 1968. The name Earl Preston was his stage name real name George Spruce. He was a MerseyBeat personality.

I never learned to read music. In 1962 when I bought my first bass, I worked on a potato farm for the summer to get it, I was cramming to pass my GCEs. That done it was Engineer school and job pressures. There just wasn't time for everything. Anyhow I ended up in one of the top bands in Liverpool at the time. Still my second favourite band I ever played in. LOL

For me the perfect cabinet was the Acme B2 2x10 three way. I liked the first so much I bought a second. The pair stacked on their ends for a vertical 4x10 was the best I have ever used in my sixty odd years of playing. I was so impressed with them that I bought a second pair.

If this little trick works for you you can just leave a short signal cable, like those between effects pedals, permanently in that position.

Wot do you expect from a Canuck?? LOL

For laughs and giggles check out . The bass is a lined fretless six string that I had never played on stage before this. LOL I'm the little old fart on the right.

I found it wonderful to watch another six string player strut his stuff. Thank you for that!

Just for the purpose of education: there is no such word as omage unless you stick an H in front of it. The correct term is Impedance.

Bassman 50 cabinet - YUCK!

LOL

I never liked the cabinet myself. Playing through one was never a pleasure.

in the upper diagram I would also connect the two negative poles of the upper drivers. Instead of two 16Ω stacks in parallel have two 4Ω stacks connected in series. If one driver fails in the diagram as is then two drivers cease operation. Following my suggestion three drivers will still operate which might well get you through the gig.

Very nice. I hope it serves you well.

Considering that a one centimetre cube of such a deceased star weighs something akin to ten aircraft carriers that would indeed be heavy! LOL

If you were playing multiple amps through the same speaker cabinet when they failed I would suggest that your cabinet was at fault as the common denominator. Were you using a speaker cable terminated with 1/4" Phone jacks?

The best 50W amp I ever owned was Leak TL50+ that I bought for five quid. I built a single ECC83 pre-amp, powered from the Leak and it worked very well. When I left the band to work outside of the city the new bass player exchanged his Bassman head for my Leak set up.

The Bassman doesn't get 'Furry' it just gets full blown distortion. If you're going to the trouble of building an amp why not build something that's actually useful?

Doing what you suggest you might run into that the amp has no top cover and you'll have to fabricate something to suit.

The UK was always 240V 50Hz all the time I lived there.

But they've got clothes on!! No fair! LOL
