VINTAGE CROSLEY KT66 PUSH PULL MONOBLOCK TUBE AMPLIFIER WILLIAMSON STYLE TESTED WORKING. Up for sale is a vintage Crosley monoblock tube power amplifier in working condition. The amplifier has been tested and produces audio output. This classic American tube amplifier was designed for a pair of KT66 output tubes and features a push-pull output stage. The amplifier is currently fitted with two 6L6GC output tubes, two 6SN7GT tubes, and one 5U4G rectifier tube. Based on its tube complement, physical layout, and overall construction, this amplifier appears to follow a Williamson-style design philosophy, although the exact circuit topology has not been verified. The amplifier includes a speaker impedance selector and internal bias/tube balance adjustments accessible through the side access panel. Current tube complement. 2 × 6L6GC output tubes. 2 × 6SN7GT tubes. 1 × 5U4G rectifier tube. The exact model number is unknown. The original factory identification label has been partially torn and damaged over time, making the model information unreadable. The remaining label confirms Crosley Radio Corporation manufacture. Based on its construction and configuration, this amplifier is believed to have originally been part of a vintage Crosley high-fidelity console system, although this has not been conclusively verified. A rare and desirable vintage American tube amplifier for collectors, restorers, and hi-fi enthusiasts. Its KT66-based design, substantial transformers, and likely Williamson-inspired circuitry make it an interesting piece of early high-fidelity audio history.

It is a push pull amplifier, that utilizes a 5y3 rectifier tube, two 6v6 power tubes, with 6j5 triode and 6j7 pentode octal preamp tubes. No tubes are included or available. Mod or convert into a guitar amp, or use it for parts, these are awesome transformers for a 5e3 or related amp.

Pilot model SA-300 EL34 push pull amplifier. This was restored with new electrolytic caps, orange drop caps, resistors, diodes, new line cord, new EL34 sockets. Please check all pictures for condition and underside on the chassis. Tubes tested my calibrated Dan Nelsen TV-7/U, see picture for reading. This is a heavy unit.

Vintage Tube Amplier Repurposed CBS 12AX7 + 2x 50C5′s Push Pull Handmade Chassis. I’ve repurposed an old CBS record player amp. It has original vintage concave style knobs, vintage power switch, and original speaker, but has an orange led for “on” indicator. You can use either stereo or mono. You only need to hook up either one of the RCA jacks in the rear for it to work. A low powered input is strong enough to power this beautiful 1950′s looking “radio” for original tube sound! The case is handmade from plywood and mdf with a plexiglass window. It has a 6 original speaker which had three very small holes in it which I repaired. I’ve run this for many hours without a problem and it sounds great! I’ve not tried it with a guitar, but it might work as a guitar amp. It has volume and tone controls. Original can capacitor and selenium rectifier were left on the chassis for show only and are not in ANY way electrically hooked up. The filter capacitors test fine with a high voltage tester to the microamp range. I only have a very basic schematic drawn on graph paper as I couldn’t find an exact schematic so I had to reverse engineer it. It is a very simple push pull design, so not too difficult to follow. Has a two prong polarized five foot power cord with a 1 amp internal fuse. This is originally a transformerless set, but now has an isolation transformer. There is NO electric connection between the chassis and the wall plug whatsoever! Note: This sale is just for the Amplifier. Other items in the photos are for photographing purposes only. Thank you for your interest!

This listing is for a Vintage 1950 Hoffman PPP 6K6 Mono Tube Amp, Ideal for converting to a Parallel Push Pull Harp or Guitar Amplifier or for restoring a Hoffman console.
