In the summer of 2009 I finally finished my guitar tube amplifier build. The amp is based on Sean Kilback‘s modified Fender 5E7 Bandmaster schematic. The modifications include a grounded power cord, modified bright cap, PaulC phase inverter mod, Pre-PI master volume, a bypassable extra gain stage, and variable bias. The schematic is below (click to enlarge):
I used a modified version of Ceriatone’s 5E7 layout (sorry, only have original layout):
Here is some info on my build:
1 * 5751 (First preamp tube)
2 * 12ax7 (Second and third preamp tube)
2 * 6L6GC (Power amp tubes)
1 * 5U4GB (Rectifier)
Uraltone TV17 power transformer
Hammond 1645 Output Transformer
Sprague Orange Drop and Atom capacitors
Carbon Film resistors
Power: ~30W
Interior of the amp. I apologize for the rat’s nest.
The top of the amp. Notice the huge power transformer.
The front panel of the amp. Ugly labeling.

Here is my second attempt on making an American IPA. This time I wanted some more sweetness, so I added some Crystal Malt, and more hop flavor, so I increased the amount of late hop additions. Below is the recipe, targeted values and a couple of pictures:

1 kg Light Spray Malt
0.5 kg Extra Light Spray Malt

10g Cascade @20 min
10g Amarillo @20 min
10g Simcoe @20 min
10g Cascade @10 min
10g Amarillo @10 min
10g Simcoe @10 min
10g Cascade @5 min

The probable label. Name and color scheme inspired by Pink Floyd.
Hopefully the beer turns out good. It’s been a week in the fermenting vessel, will add dry hops in about two weeks and bottle in three weeks.
