100 Watt Class A Power Amp
 
Has anybody the complete article of Norman Thagard
"Build a 100-Watt Class-A Mono Amp"
Published in Audio Magazine January 1995-February1995-March1995 ?
I have only the first one, I never could obtain the second and third here in my country.
Thanks.

I had allready check, the only I could obtain was

Coulomb 28th July 2002
"The Pass/Thagard project was a 100 Watt class A Amplifier published in Jan, Feb and March of 95. I will scan the schematic and post the PDF Monday night in Pass Forum under Pass/Thagrad thread."

Coulomb 29th July 2002
"I have attached a PDF of the schematic for the CLASS A 100 Watt Amplifier section. I do have all three articles available, but thought I would start with this schematic to see if there is any interest."

I have the schematics, but parts list is in the next article that I haven't
Thanks

100W class A? I hope you live somewhere cold and with cheap electricity :)

The Pass/Thagard amp article is posted under articles at

Pass Diy

in two parts.

:cool:

That one was called the A75. I recall that Norm later published
one solo.

I didn't mean to take so long to reply. I had a little bit of trouble finding all
the articles as I had removed them from the magazines to scan them previously. I would suggest building the Pass F-5 instead. The project that I am sending you is a good learning tutorial. This DIY forum is loaded with good information and helpful members. When the Norm Thagard class A 100W amp was published it was pre-DIY for me. Good luck!!!
