HP LP Filter Boards Available to Replace HT75

Hi Trolls it's been awhile since I visited here.

I had a customer ask for a single frequency pair HP and LP filter to replace his aging HT75s.
I designed a board with balanced or single-ended I/O and relay bypass and thought some of you might be interested.
The filters are 18 dB/octave Sallen-Key and are tuned to 40 Hz and 16 kHz with a Butterworth alignment.

I also have 12 dB/octave filters available on the "Input/Gain/Filter/Output" board. https://ka-electronics.com/shop/index.php?route=product/product&path=60&product_id=77

I currently have one assembled unit and one bare PC board (which can be assembled upon request) if anyone is interested.
If there's enough interest I'll add this board to my store at https://ka-electronics.com/shop/
You can PM me or use the Contact link on the store.

Thanks;

Wayne
