The manual for Hammarlund SHEETS addresses issues related to receiver blocking and suggests replacing the Sylvania type 6BE6 tube with an RCA tube, along with changing the screen dropping resistor R10 from 15K to 27K to improve performance. It also provides troubleshooting guidance for excessive hum, oscillator drift, and noisy sensitivity control, recommending specific tube replacements and adjustments to resolve these issues.

• Brand: Hammarlund
• Model: SHEETS
• Type: manual
• File size: 911.8 KB

Manual Overview

The Hammarlund SHEETS manual addresses troubleshooting for receiver blocking, primarily affecting the 7 to 50 MHz bands. This issue often arises from the use of Sylvania type 6BE6 tubes in position V3. Replacing these with RCA 6BE6 tubes and changing the screen dropping resistor R10 from 15K to 27K ohms can typically resolve the problem. If blocking persists, further adjustment of resistor R9 from 22K to 47K ohms is advised. For excessive hum or erratic “S” meter operation, replacing potentially defective tubes V7 or V11 is recommended. Calibration complaints, particularly frequency deviations, can be corrected by adjusting the high-frequency oscillator trimmer capacitor, as detailed in the manual. Noisy sensitivity controls should be reported for replacement if under warranty. The manual emphasizes careful adjustment and replacement procedures to maintain optimal receiver performance.

Quick Issues Covered

• Receiver blocking resolved by replacing Sylvania 6BE6 with RCA 6BE6.
• Excessive hum often caused by defective V7 or V11 tubes.
• Trace V3 circuit from Pin 6 to B+ bus for blocking issues.

Troubleshooting & Error Codes

The troubleshooting guidance in the manual addresses several issues with the receiver. One common problem is receiver blocking, which occurs after transmission or switching bands, leading to a loss in gain. This issue is prevalent in the 7 to 50 mcs bands and is attributed to the Sylvania type 6BE6 tube in Position V3. Replacing it with an RCA tube and changing the screen dropping resistor R10 from 15K to 27K can eliminate the blocking. If this doesn’t work, changing resistor R9 from 22K to 47K is suggested as a last resort.

Other issues include excessive hum or erratic “S” meter operation, often caused by defective tubes, particularly V7 or V11. Replacing suspicious tubes is recommended. Oscillator drift and microphonic conditions are linked to poor high-frequency oscillator tubes, while spurious responses can be resolved by replacing the Sylvania tube in V4 with an RCA 6BE6.

Calibration complaints are addressed by noting that the 100 ke calibrator is for detecting dial error, and minor adjustments to the high-frequency oscillator trimmer capacitor can correct frequency deviations. Noisy sensitivity controls can be replaced under warranty or purchased if the warranty has expired.
