Count Bassy

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.

An exact snap here. Used to love the Last Waltz but then read 'This Wheel's On Fire', which is great, but could never see "the last waltz" in the same way again. What a twunt Robbie Robinson was. On the plus side, the book made the political/a-r-s-e-h-o-l-e problems in my then band look fairly minor.

I would like to second this. I once made the mistake of reading a date code (7812 - i.e. December 1978) as the part ID and replaced a power transistor with a 12v voltage regulator (same package type). Remarkeably it actually worked for about 4 hours. Unfortunately this meant that my mistake was found by someone on the night shift rather than by myself.

There are also other 'fundamental' intervals that work very nicely, but these get modified in equal temperament so that they but work equally well in all keys - but are less than perfect in any key.

Because they're successful?

I had a minor affair with an Aeolian

I don't have one of these, but I do have a Quantum. (Bought for it's 32" scale and its compactness). I love the sound, but have moved on to 5 strings.

Did you miss the link out?

Cheesism!

But surely that can only work in one key at a time? A note that needs to be slightly flat in one key might need to be slightly sharp in another key. When instruments were tuned to a natural temperament then different scales would sound different (Eg C# would sound different to C natural, not just a semitone higher)?

So why do they call it "Temperament" when they mean "Intonation".

I think you overestimate the typical audience.
