[Amps] home brew amp

[Fuqua, Bill L]

  As a teenager I too built unshielded amplifiers. 
I just wanted to get results and then do something else.
I got my general in 1962 or 63. don't recall.
 My first HB rig was a 6AG7,6L6 and pair of 6146Bs on CW. I then went to SSB with a CE 10A which drove my 
6146Bs, and later I made a amp with a pair of 813's and then went to a pair of grounded grid 250th tubes.
The HB transmitter was shielded but the amps were not.

Arnie,  thank you for posting this.  I am glad to hear there were others whose audio came into the neighbors stereos and scrambled TV reception.  I didn't have the opportunity to become a ham during my school years, so I went the CB route and built 11 meter sweep tube amplifiers from my high school junior year, 1973 and forward, finally getting my novice ticket in 1985.  I am still building today and play with regens and am sorting out a 4-400A 6 meter amp I built a few years ago.73,RussKW6T

I've been reading about how several people on here built an amp and how it works or doesn't work
I had my General Lic. before I graduated H.S (1972). I thought I was good with electronic design and knew everything about building stuff.

My station was all, Heathkit SB 300 receiver, SB 401 transmitter, SB 600 speaker, monitor scope, antenna tuner, EV desk mic, and phone patch.

Not bad for a kid just out of High School. I thought the only thing missing was an amplifier. My dad suggested I build one, (he worked CW in the spark gap days his call was 9ccj)

so I did.

I found a pair of new 813 tubes on the old 40 meter swap net, and scrounged all of the the parts needed for a separate power supply that sat on the floor.

When it was done, I think it put out about 500 watts into a wire. I got my WAS and WATV in one weekend!!! (worked all stereos, and worked all TV) I was proud of my accomplishment,

it all worked. Shielding? i didn't have money for that so the tubes just sat on top on the chassis directly in front of a small blower. My dad was ready to

kick my ass for doing this after he had words with most of the neighbors. My point is to encourage people to continue building and TRYING things.
