12 July 2021: Due to a flood at my home/shop, Harbach Electronics is closed until I get this mess cleaned up and all of the damage repaired. Effective immediately I will be closed for 30-60 days or how ever long it takes to clean up and repair the damage. All pending orders will be canceled and refunded via the method of payment. I am sorry for the closure but I have to get things repaired and cleaned up. I will be back but it will be a little while. If you wish to order Dean Jacobs racing gear, please email me at and send me your phone number and I will contact you and process your order.
You can still view products, but no orders are being taken at this time. Sorry for the inconvenience!

FB-220 Replacement Filter Capacitor Block


SKU: FB220 Category:


The FB-220 is an upgraded replacement filter capacitor block for the Heathkit SB-220 & SB-221.  This product features high-quality computer-grade Cornell-Dubilier 210 μF 450VDC electrolytic capacitors.  The bleeder resistors dissipate about 30 watts less heat than the original Heathkit design so it operates a little cooler. The kit assembles into an easily-installed block.
