Gyraf Pultec frequencies Vs Daka ware knobs

Hi everybody
I'm building a Pultec Gyraf EQ with Gustav PCBs,
I m now designing front panel,
I couldn' t find any CLEAR info about Boost/Cut freq,
Hi boost Freq and Hi cut Freq,
Is the only way to measure
or calculate with the capacitors value ?
Or is there anybody 's got the correct gyraf Freq ?
Answers would be really appreciate,
I will share my FPD file after finishing it,
if anyone's interested.

And the info of the day :

Would be nice ! You're going for a 3HE ? 2HE ?

Nice find ! I got a few of those similary looking knobs here in NL 2nd hand (plastic), but it won't be enough for 2 channels.

Any idea about the other P'tec-knobs ? I quickly browsed that catalog but didn't see them.

Regards,

Peter

Collins-style knobs... I love it. :thumb:

Oops, forgotten about your nice page about the knobs :thumb: Had seen it a while back but has slipped my mind.

Pacemaker, just curious, are you trying to put these knobs on a 2HE front ?

Ah, perhaps better to have the various P'tec/Dakaware knob-talk on one spot. Shall we continue here ?

Hi everybody
thanks for your replies,
I will make a 3HE for the Pultec,
2HE is too small for those knobs,
I'm still looking for the Gyraf Pultec Frequencies,
Anybody knows ?
