Description: New from Scotty's Sled Shed is the Heathkit SB-303 Restoration Component Kit.A new cost effective approach to rebuilding the power supply, IF board, RTTY, Mixer and Noise Blanker boards. This kit provides modern replacements for: Electrolytic capacitors radial and axial.Replacement mylar/film caps Replacement silicone diodesReplacement 15v Zener diodeReplacement 10v Zener Diode (RTTY)Replacement (some, not all) resistors for IF board on Modulator board. I have not found a suitable replacement for ZD 513 the 56-61 Stabistor, so that is not included. If I find one I will add to kit and update the listing.This kit does not include any transistors. This kit is a one for one replacement component kit. There are no special instructions other than what is in the Heathkit manual. There are no replacements for the ceramic disc and ceramic tubulars capacitors included in this kit. Let me know if you have another application that you would like a kit built for a to assemble components for you to make you a kit for your project.I am constantly expanding the applications and continuing to build the options for vintage electronics enthusiast.

These units have lethal voltages inside. CAUTION!Buyer takes full responsibility for their own safety and ensuring they have the skillsets to install the kit.Scotty's Sled Shed LLC is NOT RESPONSIBLE for any injuries, or damage you incur installing this kit.Buyer takes full responsibility for themselves. The installation guide is a guide. You choose to use the tips or not. Your choice. An experienced technician may find 10 other ways that is better than the guide and there is nothing wrong with it. I reserve the right to substitute components. Please understand I have to navigate supply chain issues as well. Sometimes a blue resistor in the pic is NLA and I have to get black or grey resistors, same with capacitors. These parts are aftermarket. NOT OEM. If you find an issue with the components, please, please reach out to me so I can help resolve the issue. I do not mark the resistors. I expect you to either know how to read resistor codes and/or use an ohm meter to validate you did install the 100k ohm resistor instead of the 1K ohm resistor.Copyright 2024 Scotty's Sled Shed LLC.
