far better to just 'do your thing' - rather than be told how by some old perve who can no longer/if ever could perform.

Can you imagine vanilla heterosexual workshops, with demo's of various techniques ?
Social meeting spots for people to get in touch with like-minded, much applauded, but why does it always have to turn into something tacky.
Sandwiches and fruit served by ''Maid Sarah'', give me a break and a vomit bag.

Interested parties probably all work in local government and need a tasty experience to discuss at home with wife/husband, neighbours and children.😱
Who? Where?
That dude with one leg of trouser touck in sock? nah
OPS NO me never said that sorry sorry sorry...only joking😀
What do you expect in a society that put politicall corectness before common sense.
One can not even use the word gay animore
But was in not illegal to have a drink but ok to wear your mummy clothes at one stage?

Hey only asking bout squares on amps won't it blow speakers if not carefoul?
just beeing dim dodo not looking for fight
Ok, I always test my finished amps by driving them with a square wave input at a level such that the amp is not saturated. It a good check to make sure that the circuit does not misbehave when forced to slew. I also use that response to tweak the compensation to a slightly overdamped response (rounded corners, no overshoot, no ringing).It's something anyone can do with readily available bench equipment. That's all I used to do to check stability.
Using the wide bandwidth gain-phase meter uncovered squirreley behavior on amps that I thhough were OK based on square wave testing. Most notable squirreley behavior is around the gain crossover frequency, such as amps that have multiple passes of the gain through zero, or even amps that don't hit zero even with 10MHz test BW, but instead just flatten out. What I've seen tends to indicate that an output Zobel network is a flat minimum requirement. Other compensation may also be necessary. Output transformers complicate matters (no real surprises there). See my "SiC Puppy" tread for an example. See my "Vanilla" thread in solid state for an amp Gain-Phase that was finaly made to straighten up and fly more or less right.
It is my contention that unresolved gain-phase nasties may be responsible for audible artifacts, as well as antisocial behavior when something other than a benign resistive load with short cables is driven, hence my comment about cables. Cabling/speaker reactive loading may make a big difference to a marginally stable amp.
Tech rant off - resume drinking (and have one for me).

Make mine rootbeer!!!! 😀😀😀
Thanks for your ideas and thoughts wrenchcone - all good stuff!
Now were did I put my thinking cap at???? Hmmmmm - it wuz last seen being worn by one of da dachshunds I think..... 🙄

having nasty flu last few dayz ; this one including not just nasty temp of 37.5 for one day , but also each bone in my gorgeous body is center of pain 
got these ones last night , as hopefully final solution for bass helpers on my Brute Force Tann OB
found them for bargain on Slovakian small add site ....... luckily having some close friends living and working near .....
as Pa used to say - I prefer drivers on my spks have some magnet , when I asked him about Eminence Alpha 15 , years ago

When I'm dumping square waves into an amplifier input, I just use resistive load, as I like to keep my hearing more or less intact. Having said that, the dummy load resistors I generally use have an inductance of ~17 uH, as measured by that same HP4194A analyzer I'm using for G-P.

these I use sound so good I want to hear what you think of the 15s you're trying

you'll not hear much from me about their overall quality - they will be fed through some really heavy chokes , so not working much
however , I can say that I'm satisfied how they are looking - very stiff cone , lowish Mms , with Fs=29Hz
in not so big MLTL they'll have F3 around 35 Hz ,and that's my second option for them as bass helpers , in case I'm not satisfied with present iteration

Instant vitamin hit
Sugar gets it around double fast
Bit like English coffee and Italian espresso if you are not use to it U end up like Zebody
You can eat the things😱 but most of it came out again😱😱
And it aint juce as in blender shugar binds vitamins or sumthink clever like that.
Now have sumpthink pink
Why not?
