It must be kinda like being in Paradise!

Thank you Andy for confirming my memory. LOL

If memory serves me, it HAS been a long time, the UK uses a ring main system. Each branch circuit goes from the breaker loops to the sockets and finally goes back to the breaker. Current flow goes each way from the breaker to the device plugged into the socket. The local fuse in the plug protects what is between the plug and the device.

The amp itself will have a suitably sized fuse to protect it. I can't remember what fuse values are available in the UK. You can try the 3A and if it fails the 13A will be fine.

Over here DeOxit is the standard. I use their 'Fader Lube' and it works well but you only need the smallest amount! If you have 50+ years in the business you have no doubt seen some of the ramifications of over use of contact cleaner of one sort or another. I've seen the amps of folk who have cleaned their pots by spraying down the shaft. What a mess that makes.

Enjoy!

Please do not follow this advice. More pots are ruined by the indiscriminate spraying of 'magic' spray than any other.

This was before the time of Plessey. You make me feel so old but it was more than fifty years ago!! Is the 'exceedingly bare' statue still there at the bottom of Brownlow Hill?

For me the Fender Bassman was the worst amplifier I ever owned. The speaker cabinet sounded nice at low volume but getting it to gig volume was horrible. The first Fender amp I ever liked was the Rumble series.

I think all of us who do tech work have come across similar trials at one time or another. I hope your saga end with stellar results.

@uk_lefty just for interest who is Jo?

Seeing as though @afterimage didn't rise to the bait I should explain that I too count Liverpool as my home city. Yes I'm a little crazy too!! In the Sixties I worked at The Automatic Telephones plant on Edge Lane while I learned my skills and going to EE school. At the same time I played with a Merseybeat era personality called Earl Preston, real name George Spruce. On June 6Th 1968, whilst playing a gig at Nalgo somewhere off Queens Drive, I met a pretty 17 year old girl who I fell in love with. We were married in 1969 and so have just enjoyed our Golden Wedding. We came back to the city to celebrate it with our family. Forgive my trip down memory lane but it was a life changing time in my life. to all of you keep yourselves safe in this horrible time!

Oh come on Nancy love Ohmage?? The correct word is impedance! It's obvious that you know what you are doing. You use your amplification wisely. All too many people just crank the amp to get louder without giving a damn about whether the speaker systems are capable of handling that extra power. The only time I damaged drivers since 1962 is when I left my amplification in the van over a cold winters night. Stupidly I failed to allow the stuff to warm up to room temperature before dropping a nice low B into the pair of Acme B2s. I cracked a surround on one driver in each cabinet. Let me tell you THAT was a long night. <moan!> Luckily Andy Lewis the builder of the cabinets shipped me a replacement for each very quickly.

Did you get the amp repaired? Does it now work properly?

RTFM is always a sensible option!

It doesn't matter what the subharmonic does if the speaker system is incapable of safely reproducing what is coming out of the amplifier.

AMEN!

My choice would be a Mesa TT800 and forget about the big iron crap!!

Do the battery test on the cabinets to see if they are working properly. Make sure the SpeakOn plugs are wired properly and are made by Neutrik. Is there an impedance selector on the amp and if so is it set appropriately.

If you add an 8Ω load in parallel with a 4Ω load (2.67Ω total) the 4Ω load will get two thirds of the available power. In series (12Ω total) the 4Ω load will get one third of that power.

Dont bother - they're out of business now.

This all happened in the Sixties so these little gizmos were not available.

That's what I wrote.

Don't be naughty! LOL

I won't put black Nylon wrapped strings on any bass I have. I've done it three times and all three basses ended up stolen. When I got my Precision I wanted to use Rotosounds but none were available in Liverpool at the time. Finally I took a train to Manchester to buy some.
