Collins 353C-31 3.1 kHz Mechanical Filter Adapter for Collins 75A-1 RX The 353C Mechanical Filter Plug-In Adapter is a unit about the size of an i-f transformer, containing a Collins Mechanical Filter, two i-f amplifier tubes and an octal plug for inserting the unit into the socket of the first fixed if amplifier tube in the Collins 75A-1 Receiver. The adapter enables a Collins Mechanical Filter to be installed in the Collins 75A-1 Receiver with no modifications in the receiver. At any time the adapter may be removed and the receiver returned to its original condition. The 353C Adapter will not work in any other receiver. The adapter schematic is shown in Figure 1. the plug (P201) is inserted into the socket of the 6SG7 first fixed i-f tube (V6) in the receiver. The 6BA6 (V201) in the adapter replaces the 6SQ7 removed from the receiver and drives the Mechanical Filter (FL201), which may be considered as an electrical bandpass filter with a voltage step down of 10 to 1 (A more detailed description of the filter is given in Part IV). The filter is fol- lowed by a 6AU6 (V202), which compensates for the loss in the filter, and is connected into the plate circuit of the tube the adapter replaces. The gain of the adapter is the same as that of the tube replaced, but the selectivity of the Mechanical Filter is added to the receiver. This unit is untested (i do not have a radio to test it with) and could use a deep cleaning. Sold As-is for Restoration. International Buyers are welcome via the eBay International Shipping Program

On offer is a Pickett Slide Rule made in the USA, Santa Barbara, California. Included are three manuals also from Pickett. The slide rule and its case are in good condition, but the booklets have been folded in half to keep their shape. The manuals are titled ‘How to use log log slide rules’ and ‘How to use trig slide rules’, which also comes with accompanying mini-manual ‘How to use model 3 power log slide rules’. All of these were written by Professor Maurice L. Hartung and published between 1953 and 1960. There are also some plastic cards with information on the slide rule and a strap that can be attached to the slide rule case. The original cardboard box is unclean and damaged at the edges due to long time storage, please see pictures. The leather case needs cleaning as well, also due to long time storage. The item appears to be new, never used. Please see pictures carefully, as what you see is what you get. Also please ask any questions you may have, BEFORE YOU BID. I will do my best to answer them as accurately as I can.
