MeteoBridge and MeteoStick products - It works very much in the same way as my Transistor FM Superhet Receiver but uses valves and the unusual thing about this desn it will work on low voltages even as low as 15 volt if the local oscillator anode decoupling resistor is optimized to a lower value to suit. Smartbedded SB offer a range of products desned to provide enhanced data handling for automatic weather stations of various makes. The MeteoHub software program.
Dave uk The ECC86 has a cathode current of 10 milliamps per triode and will give a loudspeaker output of about 100 milliwatts from the main 25 Volt HT line at very pleasing volume and good audio reproduction. Dartmoor Railway Again Sunday 20 November, 2011, Yesterday I cycled the full route of the Dartmoor Railway again, from Princetown all the way to Plymouth.
Vintage Hi Fi - Reviewing Other Amps We It was still necessary in some cases to use valves particularly if it was a portable FM set as transistors suitable for VHF work had not quite caught up in technology until the early 1960s. Other Vintage Amplifiers & Receivers Ones We Researched But Haven't Tried We have tried many amplifiers because they interested us, see the 'Top Amps' page for all we.
Cheap Amazon Echo Deals Online Sale » Although RF and IF amplification is possible using normal mains valves at these low voltages, the power output is very limited because the emission of the cathode current is only about 1 to 3 milliamps at these voltages. If you are in a quite listening environment such as a bedroom or small office you can get usable results of about not more then 3 miliwatts of audio power from a small EL84 power valve or an even more economical valve such as the ECC86 desned for low voltage operation.
