The original spook with it's hawksford is almost the same as if you swapped
the symetri VAS.
Symetri VAS is a little slower (slew-rate) than the hawksford , but clips
better. The tradeoffs are nearly equal.
The symetri VAS would be better for an EF2 (lower Z).
I found the original VERY good , until I swapped to the K-ND and symasui.😀
OS
I'm attaching the schematic and an doc file with iron transfer the correct size. If you need more let me know.

Hi Andrew,
I just looked over my Spooky and there are a couple things you need to know. There are two jumper wires that are not used and a long wire added from A to A. I have marked in red the jumpers used and X'd out the ones that should not be used on the attached silk screen.

I think I have more fun designing a new protection circuit for every amp I build than the rest of the project.😀
YES jwilhelm very true with protection peace of mind still stuck on protection
warm regards

OS: Is there a power supply circuit board for the SPOOKY? Is there a protection relay board for the output? What about clipping indicators? It would be great to have all that in one circuit board (wish-wish). I have high efficiency horns and I want to protect them from DC offsets. Thanks, Ray
Is it possible to increase the gain on the spooky?
My dac only have 1v output so I can not take out the full potential of the amp.

Sounds like you need a preamp. http://www.diyaudio.com/forums/analog-line-level/272915-pitchfork-pre-amplifier-13.html#post4306134 This is Ostripper's design
Good evening,
I'm getting boards for a stereo Slew/KND set (thank you very much evanc) and I'm filling my basket at mouser's with parts. This was when I realized that the stated 2SC3503/2SA1381 is obsolete. Many say the variants with the K-prefix are substitutes but mouser only has different grades for them. Is this going to be a problem? The grades are D for the *SC* and E for the *SA*.
Is there another alternative?

wow ! Wolverine is alive and the SlewMaster Mini surprise me a lot for been so small amp sound like a big amp wow ! amazing sound all so clear in Spanish, "suena muy bien" = sound really good 😀
I was able to adjust the CCS to 3.6V across R10 reading no problem 🙂 I made a mistake at first to be honest on the SlewMaster Mini I switch Q101 and Q102 and burn R106 smoked well is ok is part of the learning process jejejejeje I fix the problem and is all good now, 😀 but wow I'm so happy with the results
