You’ve mentioned this SUB several times. Got me intrigued! I have two subs, a dayton audio and a jbl, they play well but never been super impressed! Ill keep a watch out for this thing! Thanks pete!
"What is that for?"
fun!
(sounds like somebody's making a diy synth)
who's VCO design are you using or is it an original?

I'm going to be inspired. That's why I have a (new/used) Instek DSO and the protoboard with a better supply. I want clean <.1% sine convertors
and <1 cent V/octave performance.
I'm redesigning both a ARP and moog filter.
The CEM(AS) 3340 is the best VCO , I could also build the ARP VCO (curve-tracing matched pairs + tempco).
VCA , LFO , sequencers are all my designs.
SMD is the way to go with any precision analog module. I won't make these look like any "DIY" creation.
Separate jack/control PCB + a main circuit module (like my amps). I will make Eurorack standard PS connections.
I even have a granular VCO that uses a AT328 (nano). yeah , programmable VCO.
"what's it for" ?? crazy music , dude !
Damn , they want 100-500$ for some of these fancy Eurorack modules. I can do better.

Amps just let you hear (amplified) sources. You can "up" the reliability , or design them to be nearly distortion free. Can't really go any
further ..... Amps are circuits to be forgotten about if listening and it sounds good. (and never blows up !).
The analog synths , you can actually design for more harmonics , or change the peaking of a filter. Different VCO's have "character" ,
more so than amps do. Moog or ARP filters sound totally different ,the music's "character" is totally dependent on the circuit.
It's cool you can design your own unique "sound".
An offshoot of this oscillator building is a function generator to test my killer amp circuits with. One can build a sine oscillator with
20-30ppm thd for this use. Or , a squarewave oscillator that goes rail to rail in .1uS (slew rate testing)!

You may want to write software synthesizers. Any imaginable sounds can be created in software.
OTOH, the sine and square wave oscillator doesn't have to worry about being replaced by digital. 🙂

That is certainly true.
But years later, nobody clamours for a Yamaha DX-7, in spite of their popularity while they were big in the 1980s/90s.
And the demand for MiniMoogs from the 1960s/70s has been so strong, they've been reintroduced!

I absolutely agree!!! But the point is they ask that price and they are getting it because of the demand!
I suspect that Korg, Roland, and Yamaha are more worried about software synthesizers eating their lunch.

Behringer has VCO/VCF/VCA for 99$. Uses the 3340/3320/ LM13700 vca. Cheap passives/controls , Circuit is good design.
Expensive VCO's use all transistor oscillator cores and Bourne/alps controls , top quality passives.
Attachments
Reasonably priced , but outsourced to Asia. Many control failures are reported (bad pots, broken jacks.)
Hi Thimios, Garden house is ready. But I am unsure about the PCB's, very tiny, no room to put the tip of my soldering iron next to a part.
Pete left an other finished version of spook in the other thread
https://www.diyaudio.com/community/...son-of-badger-suggestions.369758/post-6619823 , it's TH and I am wondering if it would be possible to combine the two designs, TH resistors and TH capacitors with the new semi's from the smd design. No work done on it though. What about you, any success?

Hi OmeEd and Thimios
Given the similarities betweem the slewmaster series, the wolverine and this Spooky and Hellraiser SMD 60W amps, I have wondered if the original slewmaster IPS's were compatible with both the wolverine and this Spooky and Hellraiser SMD 60W amps.
The original slewmaster IPS's were through hole. I haven't waded through the many pages of all these OPS amps, so it may have been mentioned that they are or are not compatible with each other.
