OM2TW's LF projects

 Some of my technical projects on LF

• 5W power amplifier - Is based on TDA2030 (or A2030). I catalogue you may find, that the bandwidth of this HiFi audio amplifier is 10-140000Hz (for -3dB, Po=12W). 5W is enough to drive an G0MRF linear amplifier. You may download circuit diagram in .PDF format.

• 1kW linear power amplifier - Just under construction. It will be big linear power amplifier based on a lot of GU50 Russian type tubes in parallel.

• LF receiver - More informations very soon...
