What is a preferred material to build them on?

No,the Carvin came with the EV in it.I tried my 4x12 with it too.Really nice! I will eventually build a cab for it like that one.This ones been down the road.Its not 100% yet,still tone tweakin and just got the trans for the relays tonight.I come across some old AJAX papers and just for fun I am see...

I know that Jim Seavall (Scumback Speakers) has stated before that the Celestions take many, many hours to break in. I must agree,My 4x12 has the 65s in it and they're just now coming around,been in there for over a year.At first I thought something was wrong with them but after a while it got MUCH...

:oops: :oops: :oops: :oops: :oops: :oops: :oops: :oops: Found the problem.I really like to complicate things if you cant tell already... The jack switch on the return to power amp was defective.It was not closing when unplugged.Thanks for telling me about running the different pre into it.Thats how ...

I have posted a few threads on the 124 I have been building and it is finished except the supply for the relays (temporarily using 9 volt batteries for testing).It sounds great.Absolutely without second thought,the best sounding amp I have ever owned!One final problem. VOLUME! It is not near as loud...

Its so funny,his named is walked around like Voldemort's is on Harry Potter."He Who Must Not Be Named" or "You Know Who".

Coincidence? I think not. JK Rowling is a long time lurker on this forum.

Does Alexander the Great even have a website?

Man not only are you guys an amp library,youre just damn entertaining!!Let me think of a REAL good question!!!

Got it.Thanks!

Cool.Thanks Mr Smith.Seen it a lot and didnt even know what it was called.Could one of you point me to a link of a layout or schematic of that?

What is "HRM"?

Cool,not trying to jack that thread but I am having the same problem. I made an error on the last post.I have the 4.7 /1uf/390 now and its way to dirty.At the high end of the pot it makes a quiet but very high pitched whistle.Like positive FB.I think Bob has explained this to me but it was some tim...

That will be easy to sub in values. Do you think it's best to leave the tail resistor at 390R when subbing in different NFB resistor values? The shunt resistor value 390 is usually fixed by the phase inverter design requirements, and the series resistor is then sized according to the desired amount...

Youre right.I tried a Fender type tone stack and one like the boogie mark II and either way it sounded pretty rough.Guess it just wasnt designed for that.I have put the PAB and Rock/Jazz switch back in.A little better.For some reason my bass and mid isnt working,the treble is acting like a tone cont...
