Hi JPK,Coming soon: Sound Skulptor EQ250 Stereo Parametric EQ for the 500 series.
More details in the first post.
When do you think these will be available?
Can these be customised for indented knobs for recall?
You mentioned inspired, what would be the differences between the original - do you have different curves, frequencies, etc. is the sound quality the-same, or yours is cleaner, low noise?
Thank you.
The EQ250 will be available in 2-3 weeks.
The potentiometers are typical 9mm pots which do exist with detents (11, 21, 41). But they are not standard and you will probably need to purchase a large number.
The main difference with the original is in the use of modern OPA134 and OPA2134 op-amps, allowing the removal of some coupling capacitors. So IMHO same or better sound quality.

Not that I know much about opamps, but weren't the opamps used in various Sontec designs extremely high fidelity, and running on quite high voltage rails?
Do you consider OPA2134 equivalent or even superior to these? What was used in the 250 originally, HS or 990 or something else?
I see companies like JLM selling modern incarnations of various of these opamps (HS ? ), and they are all very expensive, linear frequency response way into bat territory and running on +/- 24V to 30 or so. I don't question that an OPA2134 is a high fidelity product, just curious on why one would be enticed to spend 200$ on an "original" HS opamp instead.

When Sontec was launched in 1975, the best op-amps available were the TL071 and NE5534. This is probably why they preferred to build discrete op-amps for the input and output stages. Today we have the OPA134 and THAT1646 which are excellent in terms of noise, distortion and offset, even with a lower suply voltage of +/-16V.
