Mini Aleph

C1-C3 220uf P10326-ND footprint allows for 12.5mm diameter caps (35v will work if rails are below 35v) 

C4 10pf 338-1090-ND mica capacitor - CD5 package 

C5 1nf PS1H103G-ND Panasonic ECHS PPS film 

C6 47nF BC2068-ND BC Polypropylene 47nF capacitor for D5

 install a 500ohm trimmer on R8 and preadjust to 250ohms.

100k pot for R13

500 ohm pot for R8. 

Initial Test

Using R13 I am able to get the bias up to ~1.17v (.550v across .47ohm source resistor)
