##### Capehart and Rider's schematics

**Overview about Rider's schematics for Capehart and Farnsworth-Capehart**

**For getting a good list of the Capehart models and to have data complete, I made a working page about schematics and tubes which could also help others. Here you find the main article about Capehart models.**

**Hugo Gernsback "Official Radio Service Manual" was actually before Rider.**

In the volume with copyright 1930, we find a note on page 4: **"Capehart Corp."** See **Webster Electric Co.**, page 350. There is to see the only schematic for Capehart: 6013 5-tube Power Amplifier used in **Capehart Orchestrope Model 28-GB**: Input transformer W-412, followed by tube 27, transformer W-254, 27, transformer W-438 for 2 x 45 in push-pull, 280 with power transformer W-671. For **JB and JD models** the output impedance W-631 is omitted. 6 resistors, 7 capacitors. Input 115 volt AC.

**Gernsback volume II 1931-1932**

Supplement page 4Hb Capehart: schematic models 200 and 300 de luxe 11-tube automatic Phono-Radio with visual tuning meter with 58 RF, 56 osc, 58 det, 58 IF, 56 det, 56 AVC, 57 silent tuning, 56 pre amp, 2 x 47 push-pull, 80 rectifier. IF 175. **Produced by Howard Radio Corp. as model K** chassis with change by Capehart it is CK (pickup amp). Model 200 uses a **Jensen** D9 12" speaker, model 300 a "Mastodon" 14". Cabinet and changer are different. Power 142 watts for for undistorted 5 watts output. Needle weight 5.5 to 6 ozs. Changer adjusting for the **"10-12-C" record changer**.

For Capehart see Webster Electric Co. with reference to volume 1, Page 350 for models 400, 401, 402; Supplement = 2-stage **PO amp Code 6005**, **6009, 6025 JD amp** on 350A and **3-stage PO amp 6030** **JE** & **B-37-50** amp on 350B. Pages 350C (tuner) and D (amp) not found, the same as in vol 1?

Page 496 is for **6013 Power Amp.** (2 x 27, 2 x 45 and 280) and **35TA Power Amp**. (2 x 326, 2 x 310, 381).

**Rider's first volume had no number****Page 192-A**: Schematic for **13-tube Tuner/Amplifier for 400, 401 and 402:****51** RF, **27** osc, **51** 1st det, mixer (translator), **51** 1st IF, **51** 2nd IF, **27** 2nd det, **24** amp, **47** **47** **47** **47** to and two in push-pull, **80** **80** two rectifiers. Speaker field, output transformer for 3 possible loudspeakers. Actually the tubes are 551, 127. Two chassis.
