I am now appraising my collection of valves and shall be selling some on a private basis. Since the prices for some audio valves are volatile, I shall be putting some on eBay (Electrojumble) rather than quoting fixed prices. If you require particular types, I can select and put them on auction for you. Types possibly available - HERE
Many part used are available. These have usually been taken from working equipment or radios. They are quite adequate as replacements in domestic radios and televisions and other non-critical applications and have many years of useful life remaining. These are guaranteed on a refund or replacement basis if you are not satisfied. The prices are usually 30% of the unused price. Please ask if you require advice on replacements; I may be able to help or advise you where to find one.
For Transistors/Diodes or Integrated Circuits (ACTIVE), please click on the titles above to take you to the page.
See Tech Data for Mullard data sheets for ECC81, ECC82 and ECC83. (33 pages)
See Valve Bases for the connections to valves in 1934.
For Tube/Valve Rectifier Comparisons see - 4V Rectifiers or 5V Rectifiers These tables give an approximate comparison of the voltage and current ratings together with the heater currents. This is useful as a general guide to possible replacements but care should be taken as parameters such as the maximum permissible peak current ratings and heater-cathode voltages may differ.
