Ramsey Electronics PR20 manual Troubleshooting Guide, Conclusion

TROUBLESHOOTING GUIDE

The only possible causes for malfunction of the PR20 are faulty or incorrectly installed parts. Re-check your work. Transistor replacement information is provided. Poor performance such as oscillation can be caused by bad parts-mounting (excessive lead length of resistors or capacitors). Erratic operation will be traced to poor input, output, or voltage connections, or a faulty solder connection.

CONCLUSION

Please make sure your preamplifier is working as originally designed and that you read the terms of the Ramsey Kit Warranty before attempting any modification of your kit. We hope you’ll enjoy the added receiving performance offered by your Ramsey PR20 and that you’ll look forward to building other Ramsey kits for VHF, HF...and for fun!
