It is based off of the A035 Hammond Reverb Amp (and similar to a IIb Lite). I wanted to recycle my amp chassis, lamps, etc... to make a 18 watt, 2 EL84 Class AB amp. I realize I am a much better tech than builder---but it is a fun learning process regardless! I have included all of my mistakes so everyone can look and say to themselves, "...why the hell did he do that?" Here is the link to all of the schematics, layouts and actual build photos (including all of my mistakes)! http://s5.photobucket.com/albums/y199/CannonFodder187/phoenix/ I have sound samples recorded with a Tascam DR-1: Sample 1: Phoenix through 112 Celestion Lead 80 in an undersized Carvin combo cab. http://soundclick.com/share?songid=6795675 Sample 2: Phoenix through 212 closed back cab and a MXR Carbon Copy. http://soundclick.com/share?songid=6795683 Sample 3: Phoenix through 212 closed back cab, modded BOSS SD-2 (both channels) & MXR Carbon Copy. http://soundclick.com/share?songid=6795691 Things I am not real happy with: 1) I wish the overall voltage was lower. Hammond transformers are rated at 110V, not the 123V AC coming from my bench outlets. My DC voltage is about 10-15 volts higher than I would like them to be on everything. I really need to get a Variac. Still, it is ok.... 2) The tone control sounds best around 5 o'clock. I wish there was more range from treble to bass response. Once you dial it in, you are fine. Check out Sample 3 when I sweep the tone knob (around 1:50). I might have to change that up. I am debating on a 5 position switch with an ES-345 RC tone matrix...I want to gig it a few times to determine what to change. 3) It is 1:23AM and I want to crank it up...but my wife and kids might object. I guess I will have to wait until Friday to gig with it. I might need to make it "prettier" this week.
