There's "technical write-off" (eg parts no longer available) and "financial write-off" (ie cheaper to buy another one). Your tests would suggest that the damaged fuse holders are the only problem, so it's not a technical write off. I can only think that he thinks it would take too long to strip it down and rebuild it. Depends how much it would cost to buy another one I guess. Possibly he didn't feel up to the job and didn't want to admit that. If you're handy with a soldering iron you could Solder a new fuse holder onto the stubs of the old one. I do wonder how internal fuse holders like these got broken though.

Rather than conductive glue you could just solder the fuse to the remains of the holder.

Newtone also do round cores!

Yes, sorry, it was a bit abrupt.

RMS can also be used for current, and can be used for power as long as you take account of the power factor. Hopefully not patronising note to those who don't know: Power factor takes account of the phase difference between the voltage and the current. In a pure resitive load load this is '1', but when you get inductance and capacitance involved it is usually less than one. Fairly easy to calculate, or measure, with sine waves, but very complicated when you have a 'random' signal as in audio. It can never be more than 1.

Depends on the actual wording you used in your questions. According to your own post the first time you asked on the phone you asked if it is good for UK use. They answered correctly that it was. When you got there you asked if it was good for unlicensed use. They answered correctly that it needed a licence . As I say, it depends on exactly what you asked them on each occassion. Obviously if they'd qualified their first response by saying it needed a licence than that would have been good.

How many consultants does it take to chnage a light bulb? None. Since when did a consultant change anything?

It's an output jack.

Probably felt sorry for you.

Not so much at Giogs, but I'm amazed how many pretty decent restuarants follow up a good meal with really crap coffee that tastes like mud (well it was only ground only 10 minutes ago, sir)

Who he/she?

Sorry to perpetuate the OP's embarrassment, but I've just been directed here by a mod.

Bit of a continuity error at 37 - 39 seconds in.

Could you leave the crease but strengthen the area with some glue to prevent it getting worse?

Yes, I saw that as well, but as it didn't appear to be damaged assummed that these were not the ones the OP was talking about. Note to the OP: If this is the item that needs replacing then it's a pretty easy soldering job - Once you've stripped the amp down to get to it!! . These tend to be through hole mounting, so you'll need to get access to the back of the board.

Yes, I knew that Bill, hence my point about impedance being the complicated one & resistance being the simpler one. From the net (other sources are available😞 impedance /ɪmˈpiːd(ə)ns/ noun noun: impedance; plural noun: impedances the effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.

I must be blind, cos I can only see one fuse holder there without a fuse in it. If the springy bits have justmoved apart you may well get away with forcing them back together again with some pliers and then spring the fuse back in. The fuse holder I can see does seem a bit discoloured though, possibly due to sparking in the past, so you'd want to clean that up as well.

Bill, I'm very relucant to question the master, but surely it's the the other way round? i.e. impedance that covers the combination of factors that you mention, and resistance which is used for passive resistance. Hence a coax cable having an impedance that is independent of it's length (at Radio frequencies at least)?

Stupid question, but if you can't log in then how do you notify the mods?

Would that be the Ideal-Standard?

With industial servo amplifiers (to drive motrors) you tend to get a specification such as 6 amps continuous, 18 amps absolute peak for 2 seconds, 10 amps for 10 seconds etc. and generally get some sort of graph showing current again how long it it will deliver it for. However it is all very complicated, for example if you've just used 18 amps for 2 seconds, how long before you can do it again? If after the first 18 amps for 2 seconds it goes back to zero then you might be able to repeat it after 4 seconds (i.e. the average over 6 seconds is the continuous rating of 6 amps). If after the 18 amps for 2 seconds it drops back to 5 amps then you might have to wait 26 seconds before you could do it again. It all comes down to "Duty Cycle", but it's all very complicated. With servo drives you tend to work out what you think it needs, add a bit for luck, and see how it goes. This is why a lot of industial motors and drives are over specified - i.e. it's cheaper to over spec it than to underspec it and have to replace it.

You may well find that amplifiers specify a minimum load of say 4 Ohms for each channel in standard mode, but 8 ohms minimum in bridged mode. This should be clearly marked somewhere near the speaker connections. However the ohms of a particular cabinet will be fixed and does not depend on how it is driven.

It obviously worked, but an OBBM cable would have worked better.

Unfortunately it's very easy to 'Like' a band on facebook. Actually going to see them takes more effort.
