AND?

What you do need to be aware of is buying gear from Canada or the States. We don't see too many units with switchable input voltages. 240V sent into something that expects to see 120V is always fatal.

It's appaulling how many Pauls are on this site!! More seriously, were all the repairs done at the same place? Were the faults the same each time? If so I would be having a conversation with the service manager. I would contact Ampeg and ask their advice. You won't be any worse off than you are now and they might well offer you suggestions for going forward.

So they are now defunct? They made good equipment for a reasonable price. I play their basses. Their power amps are in everything I own. <Sigh> Family squabbles IIRC. I trust you and yours are safe and healthy and that you have a merry Christmas. Paul

Get yourself a BX1500. That will handle 2Ω. on each of it's two power amps. If your cabinets are both of the same model you could run them in series for an 8Ω load. Different speaker systems in series could well interact poorly.

AER Amp One comes to mind.

Only if you are very, very lucky and In this case I doubt that the valves have anything to do with the original problem!! Besides, it being an American made unit them valves is Tubes.

I don't think Andy is destitute! LOL Maybe autocorrect spell checking got it wrong?

Obsolete junk - definitely!! lol

Very often a cabinet NEEDS sufficient power to get it moving into the sweet zone. My Acme B2 boxes sound ho hum with a lower power amplifier. With enough power they are wonderful and a low B just leaps out of them. Just to be fair I drive them with Class D amplifiers. Enjoy your new toys! LOL

I'm glad you sussed it out!

I hope you ordered the four pole version.

Break a string at the gig!! Kinda like break a leg! LOL

There is no real way to mess with impedance. Yes you could use a transformer but it will be both heavy and expensive. The unit mentioned above will change 4Ω to 8Ω so you would need two - one for each cabinet. All four of my Acme B2 2x10 cabinets are 4Ω. Then again all of my amplifiers are happy into a 2Ω load. My power amps will drive 2Ω per channel so they can push all four of my boxes at once. In your case I would pick up a stereo / two channel power amp and drive it from your existing amplifier. These are pretty cheap for what they bring to the table.

I see I have responded to a zombie thread!!! It must be time for a nap

Circuitry drawing too much power. Tech Time!

Did you try the old favourite trick of linking the Send and Return of the FX loop with a short signal cable?

<Sigh>

You really shouldn't have to go through this crap with what is supposed to be a good quality amplifier!

It sounds so good 'cos that's the way they designed the brute!! LOL

Simply put no. There may be a small gain depending on the efficiency of the driver you select.

Better too many fans rather than too few! You must be a Republican! I'm kidding! LOL

Indeed, to get the best out of any topology the power supply feeding it has to be adequate for the job.

Just for interest why didn't you just buy a power amp for the Sadowsky to drive? I would have thought that would have been cheaper.

Heft doesn't come from the class of a power section. My Class D power amp gives everything I can ask of it in a 2U package that's very light. Everything I own is based on Class D technology.
