Found this. Maybe it'll be helpful.
no, because of his conduct overall...
we (I at least) believe that debate should be made in good faith. When people are obstinate & when nobody is buying, start a new thread to push their nonsense (he did that here & in other threads where he was being obtuse) & try to say that everyone else is erroneous, making every thread about him & his argument, well, it's just disruptive argument ala trolling.
Most of the argument wasn't to push people to explore differing ideas, methods, etc., they were meant to try to push the buttons of the person on the other side.
If this thread would have been the 1st (or 2nd) instance of this, we would have simply warned him. The fact is that he's done this in most threads he participated & was duly warned along the way. He predicted (in PM) that he would get canned anyway...
Thanks Belial !!
a bloody bullfight.
But NOT why I came here...
I came to find out, to learn, about Marshalls generally, mine specifically.
Not to watch inflated egos goring each-other round and about in circles over who pisses the highest.
Heck - had way too much of that at... some other places. Glad to say that most here are above that kind of crap-fest
Another question !!
Did I dream or I've read that for Solid State amplifiers,...........the mismatch is the opposite !?
8 ohm on an SS amp would work with a 4 ohm cab .
I don't care for SS amps but I'd like to know if what I've read is true !
You can run a valve/tube amp into a spanner - it won't hurt it. But don't run it in to thin air - it WILL hurt it.
You can run a solid state amp in to thin air and it will be fine, but run it in to a spanner and it will die rapidly.
Of course, responsible & sensible players rarely use spanners to gig with - the frequency response is dire...
I think with SS amps you need to know the minimum Ohm load the amp is rated for. Going below this overloads the Output Transformer. And do not run one into thin air. I did this momentarily by mistake once. There was a wisp of smoke and a burning smell immediately. I got very lucky as I noticed straight away and turned it off, saving the amp!
So if the amp is rated for 8 Ohms (or the rating of the factory installed speaker/s if you are in doubt), a 4 Ohm speaker load is too low. Going above is fine (i.e. 16 Ohms into an 8 Ohm amp) , though the output of the amp will be reduced.
By the way !.......what the heck is a spanner like Nik mentioned ??
I would like to know what a "spanner" is also.
Do no run your amplifier any other way except as the manufacturer intended or suggest. There are solid state amplifiers that will die without a proper load/speaker cabinet attached.
I think that the use of the word "spanner" by @Nik Henville was in reference to an actual spanner (USA=wrench).
Do not connect your amp to a spanner, they sound too metallic.
But if you run your valve amplifier into that type of spanner it will die.
Nik said it would not hurt so it must be a different spanner.
I think @Nik Henville should clarify his position on the tonal qualities of amplifies spanners himself.
Fender uses shorting jacks for their outputs. Because tube amps generally will survive a dead short for a while.
Accidentally unplugged the speaker on a '74 Deluxe Reverb once. 40 years ago when I was even more ignorant than I am now, so like a dolt I turned the amp's volume all the way up and futzed around for a few minutes.
I could hear the output transformer singing.
Plugged the speaker in and all was fine. One of the 6V6s died a few months later. May have been related, but I cranked that amp up all the time so might have been unrelated.
Not saying that amp would always survive that, and I'm not saying all tube amps would survive that.
Just saying tube amps are more likely to survive shorts than opens.
spanner - as in short-circuit, copper buss-bar, car jump-lead, whatever.
open-air - as in open-circuit, nothing connected, no load at all of any kind
Valves / tubes must ALWAYS have a load and NEVER be played open circuit
Solid State must NEVER have a short-circuit but is happy with no load
The only spanner I will play through with my Marshall is the Chicago brand 9k White Gold diamond encrusted 13mm/14mm open-end ratchet spanner US Pat.C3 56278. The open ends allow it to sing, and the ratchet just gives you that extra "adaptability" for gigging different sized venues...
I sm sorry but a short circuit across the OT secondary is not a good thing but rather a bad thing just like an open crcuit.
That is still gambling. Something will go poof. It is just what goes first and hopefully it is the fuse.
Did you get nice Overtones !?.........haha!!
Happy it didn't burn !
You must be a Poet Nik cause even though I'm not a tech ,..It was easier for me to understand the
Voltage Doubler dilemma than the ratchet spanner thing !!
I'll keep trying !...........I'll get it sometime !
Are we going to have to start calling him Henman?
