As someone who worked on several Nuclear power stations I found the stickers somewhat amusing! LOL

I. have an old Heathkit tester which I use for quick go/no go checks. I also have a Hickok tube tester that gets very little use.

It's called a tube tester. There are modern testers available for a limited range of tube types such as those pre-amp tubes used in MI amplifiers.

Pre-amp tubes should last decades as they don't do much work - lazy buggers!!! LOL

I don't have a clue who Alan Partridge is so it went over my head bones!!

Was this aimed at my post?

You'd better eat your Wheaties before you try lifting that beast!!

'Stereo' doesn't work too well for bass. I tried the idea in the early Eighties with a JBL K145 + a pair of JBL K120s on each side of the stage. It worked well, or so I thought, from the stage. Out in the room not so much with cancellations in different areas. Don't try changing the drivers in the jBL cabinets as they are designed to use the driver that's installed. Anything else would be a downgrade no matter how good the driver might be.

Phil, I think that unit is a line level box not speaker level. I couldn't see any reference to speaker connections.

I haven't used a pick since the Sixties! Using my fingers seems so much more organic.

The lesson to be learned is don't look at what you don't want to see!! LOL

WOW! We've had a Pandemic since the next from last post!! LOL Edit: I hope everyone is keeping safe. My brothers tell me how bad it's been.

Well good luck with that then. I hope you get the amp fixed.

Sorry to disagree but the typical 4x10 will put out more lows that a typical 1x15. The larger cone is meaningless as it's mostly other characteristics that lead to lows.

I know you have dismissed a B15 but if you can get your hands on one they are worth every penny. They make practice time a pleasure and not somewhat of a chore.

I too remember the name but that's as far as my memory goes, sorry.

My preferred speaker system is a pair of 2x10s, Acme B2, stacked on their ends on top of each other for a vertical 4x10. The dispersion out in the room is far better that way than any other arrangement! With one cabinet the same applies. If you think that adding a 15 will add more lows it's not always the case.

Just to make it clear you can connect two of your specified speaker cabinets to your amp safely.

My first question would be what experience do you have servicing solid state electronics. Just 'cos you've owned the amp for ages doesn't mean that you can play fast and loose inside the amp. in general doing so just causes more damage than already exists. Do you even have a clue what to look for?

For a start we are locked down!

Swine!!!! I so want one of those amps! Enjoy!

It's kinda normal for a fan cooled amp to need it's cooling path cleaned out. Anyone who does this task should wear a mask as you don't know what crud the amp has sucked in over the years. Masks should be easy to find at the present time - unfortunately!!

A choke is the most likely explanation. For US models they would typically use a different power transformer or one with taps to suit the local mains voltage.

Two weeks later, what news?

I find it ironic that folk are looking for distorted sounds. We, of a 'certain' age, would have given a left nut to be able to hear our basses cleanly and without distortion. Distortion was pretty much all we could get!!! LOL
