FS: Pultec EQP-1A, MEQ-5 and custom inductors in RM8 format (Group order?)

Same inductance and resistance as the original. The resistance part is ofter overlooked by many home winders it appears...

Stereo matching within a couple % is no problem.
€18 each. I would like to have an idea of how many of you that are interested in these. Please make a post if you are.
If you're just vaguely interested, please hold until you know.

For the custom inductors: To get an idea of what is capable, maximum is 700mH at 40ohms for example. 
If H is increased, R is increased and the opposite. This is not linear however. 1H may get you an resistance of 50ohms.

Shipping, tracked, insured up to €200 is €15-€25.

No? Maybe we got saturated on them coils. Speaking of. I'm using the cores with center hole, which makes a huge difference in how large a voltage swing they can handle.

Hi Chrion. Are you back in the inductor winding business again?? Hope you are well now.


Cheers

Hi Ian,

Thanks for caring. I might be. Just want to check out if there is any need first. So far, the need seems very low. Business is not very good atm  ;D

Pm'ed you

What cores are you able to offer? I am in the process of designing a mastering EQ which will need a range of custom inductors, closely matched for stereo operation. I have a customer for the prototype so I able to place and order. Once it is complete I will be offering the PCBs here and they will all need inductors.

Cheers

I will be doing Ian's project should easy access to inductors is available!

Sure, custom values are no problems. I use a RM8 cores with center holes and gap. Tolerance is very tight and saturation due to high signal should't be a worry in most designs. Especially not the pultec and Ian type EQs.

I need a pair of the 477 / 625 for the mid eq

okgb: your PM-box is very much full. Are you interested in buying the pair, send me a PM
