Replacement for Motorola HEP-S100 and Opto sensor GE H13B1/2

Hi :D I am looking following parts and not able to find online stores. Motorola HEP-S100 Transistor and Interrupter sensor GE H13B1/2. Or any other replacement part numbers would appreciate. These parts for upgrading my linear tonearm (Rabco SL-8E) servo drive. Thanks in advance for the help.:cheers: Rajkumar

Hi Rajkumar,

I am trying the same right now.

The GE H13B2 is on ebay in Southern California.

I did not find a data sheet for the HEP-S100. Seems to be a generic constructors parts line similar to NTE or ECG with wide spec. range.
The original Rabco SL-8E circuit uses 2N3705. I will try some BC337 I have on hand.

Rajkumar,

You are jumping the gun.

This is my circuit that you lifted from my post on another forum:

That circuit was for a radical modification and will not work as a simple retrofit for a stock SL8E. I have developed a new circuit that will work as a simple retrofit for a stock SL8E, and will be starting a new thread for that very soon, complete with updated schematic and currently sourced parts list. Please be patient.
