About RF Cafe
Copyright: 1996 - 2024 Web BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images

Stromberg-Carlson Nos. 62 and 63, 8-Tube High-Fidelity Chassis Radio Service Data Sheet
|

All voltage readings are measured between chassis and ground with a 1,000 ohms-per-volt meter. The line voltage is 120 V. for this table. All filament voltages are 6.3, except for tube V8, which is 4.85 V. The set should be tuned to 1,000 kc. with no signal. The numbers over the columns correspond to the socket terminal numbers which are shown on the bottom chassis drawing. Note that there will be no high voltage in the circuit when the speaker plug is removed. The tuning meter is used only on the No. 63 chassis, but the two are otherwise exactly alike. The variable intermediate transformer is used as a band widener for high fidelity. See Tom Bavis' AudioPhool.com website for an extensive collection of Stromberg-Carlson photos, datasheets and Sam's Photofacts files. Stromberg-Carlson Nos. 62 and 63, 8-Tube High-Fidelity Chassis
