For sale we have a rare fully restored Pilotone AA-901 Hi Fidelity Amplifier, serial number 6546. We obtained the amp from the 91 year old son in-law of the original owner. While the amp was taken care of over the years, it had not been used in over 30 years. Physically the amp is in very good shape, it has some blemishes and scratches, but there are no dents and the paint and lettering is in good shape. While not perfect, the amp presents itself very well. The amp was thoroughly gone through. Both main filter caps, as well as all electrolytic and all metal film capacitors were replaced with modern caps. All resistors were checked and replaced as needed. New tubes were installed using Modern Genalex Gold Lion KT66 power tubes, and Electro Harmonix 6SN7 tubes. The RCA 5U4G Rectifier tube tested strong on our Amplitrex AT1000 tube tester and was reinstalled. We also replaced the power indicator bulb and the red lens.
The amp has been biased at 40 volts as per spec and the tubes have been balanced. We put about 4 hours on the amp since and it sounds great.
Shipping is included in the purchase price to the lower 48 US.
All tubes will be removed for shipping. While we don't have the original box for this unit, we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, polystyrene, and or instapak when boxing up our gear for shipping.
