This linear amplifier was made on 60's by Henry Radio in USA. It's very heavy unit console due to the heavy duty
transformer. It uses 2 tubes 3-500 ZG by Amperex. Using 80 Watts from Kenwood TS 930 to drive the Amplifier, it will give 1 KW with 1.6 KV reduced voltage. The original voltage is 3.2KV, so this unit can give 2 KW PEP.
I have reduced voltage to safe the tubes.
Tudo depende do estado, da marca das valvulas..do estado das valvulas. Eu conheço apenas 3 radioamadores aqui em SP que possuem um linear da Henry. Mas para vc ter uma idéia + ou - uns R$4500..esse modelo igual ao meu.
