I have been designing and building various devices from a multi
channel mixer with all the hardware to hold an outdoor concert. I
also have origional laser lights etc. My last project was a 1000 watt
ultralinear twin channel valve amplifier.
All the work i have ever done was my own i used magazines like eti
for inspiration only many articles had serious errors in their
calculations. And some magazines their products were at a standard i
wouldnt waste my time building. I am fully self educated learnt the
hard way. Now got spreadsheets and the like. Making it much easier to
design a piece of equipment. I was willing to share some knowledge
but not now a few idiots has changed my mind.


I'm so pleased that you've decided this group isn't worth your time.

Don't let the door hit your arse on the way out.

1000 watt valve amps have always been plugged into a very large
alternator. I couldn't state how many amps the pair draw it was just
a number when i built them. Just not important enough to remember.
Then could someone out there tell me the biggest amplifier that has
been built?


How Chinese! State a big number but don't actually measure ...

Anyway the 1000 watt pair i built you need quite a few speakers to
take the wattage. Not to mention the transformers i just built it not
interested in the manhandleing of it. I think the transformers are
over 90kg each. The biggest valve amps were used to transmit am radio
signals 20000 not uncommon i think 40000 was about the biggest. Could
be why they went to fm radio.


That or the facts that solid-state components are lighter and FM has far
superior fidelity.
