Mystifying Herzog Schematic

[The New Steve H]

I ended up ordering the big fat 10 ohm 5w resistor with the heat sink. I figure I'll screw it to the chassis.

I'm using all metal film resistors this time, except for power resistors, which will be wirewound. Hoping to cut the hiss. I know this thing is going to be run distorted as an effect, but it can also function as an amp head, so might as well do a good job.

How do you like the sound? I mean when you use it as an effect.

It's been a while since I've fired it up, but it sounded great as a stand alone amp (plugged into a pair of vintage Jensen P12Qs) and ok in front a the fender blackface clone (all I had at the time). I think it would sound better through something without a mid scoop to let the mids through a bit more. It sounds a bit muffled, needed some more crunch.

My plan was to put it in front of an Ampeg V4 that I have never gotten around to re-conditioning.

If I remember correctly, I used MF resistors and Mallory 150 caps.

A problem with two fuses? Really? You must have less than zero experience with repairing guitar amps, cars, trucks,ATVs, appliances, or anything else with fuses that are accessible to the end user. The internal fuse in series is an idiot resistant safety measure for people who think, "Hmm, if that 1 amp fuse won't hold why not try using 2 amp or a 5 amp or a 10 amp or maybe even a 20 amp fuse? Nothing bigger than 20 amps will fit and my amp smells like smoke now. They all kept blowing until I got up to 10 amps and then my amp caught on fire." I use internal fuses all the time, and when I could still get them, I used locking collet bias pots too. The less stuff the musician end user can adjust or change by himself/herself/themself/itself, the better. Crank the collet nut down on that bias pot and the customer will need large pliers clamped onto the screwdriver to turn it. External bias test points are stupid too. Randolph Bachman would have likely used the Herzog with a Garnet BTO amp. BTO at Garnet stood for "Big Time Operator" or Garnet's flagship amp. Their lesser amps were rare items to encounter at the southern border, but they never inspired me very much. The old Canadian made Traynor amps were built much better. (tougher) Guaranteed for life, tough. And they had a rent to own program where your $400 Traynor amp only cost $1000 when you finally got it paid off.
