Vintage Original, serviced and working great. Gibson BR-9 10W Vacuum Tube Combo Guitar Amp. This is an original 40′s BR9 it has been serviced and is working great. It’s not the prettiest amp, but sounds great. Still has a 2 prong power cable. Please if you have any concerns feel free to ask!
Hammond AO-35-7 Tube Reverb Amplifier – Technician-Owned. Original Hammond AO-35-7 tube amplifier from the personal collection of a longtime Hammond organ service technician. Originally pulled from a working organ, this unit was later professionally configured and used as a dedicated reverb amplifier in a custom stereo jukebox system alongside a 6550-based power amplifier. It spent years in the technician’s private collection and was functioning in that application when last used. The chassis has been refinished in silver-gray enamel and presents well. This amplifier is currently configured as a reverb unit and is not set up as a guitar amplifier or hi-fi amplifier in its present form. Please note that the amplifier has been in storage for several years and should be inspected and evaluated by someone familiar with vintage tube equipment before being placed into regular service. An excellent candidate for. Hammond organ restoration. Tube reverb projects. Custom audio builds. Guitar amplifier conversions. DIY tube amplifier projects. I have more of these available for those interested. Please review photos carefully and contact me with any questions.
Amazing Bell Model 3715 Tube amplifier from the 1940′s. Incredible fuzz distortion when cranked. Works great, sounds great. Think ry cooder, Blake mills, film-o-sound, etc.
4 6BQ5 RCA 1960s HiFi Stereo Guitar Amplifier Vintage Vacuum Tubes Strong & Balanced. Tubes Tested on a TV-7D/U Tester. Tubes Test New, Strong & Balanced 78. They did not have individual boxes… Some of the logos have rubbed off a bit, but they test New & Strong..
I’m letting go of a few things from from my collection, including this Lafayette PA-622 vintage tube amplifier project. These make killer guitar amps! This is #2 of 2 I have listed. The exterior case has some wear, but the amp itself is solid – needs typical updates like new. Servicing, desired mods/conversion – pictured tubes are included – 7189 Mullards!
Here we have a beautiful 1947 Gibson BR6 amp. This is the much rarer 1st edition that was only made for a couple of years. This amp is in very nice shape considering it’s close to being 80 years old! Fully restored with the top notch parts! Plug and play ready! All of the caps have been replaced with Blue Sozos and F&T electrolytics. New Carbon comp resistors where necessary. 10 Rola field coil speaker is in great shape and sounds awesome! I had to replace the input jacks and the volume pot due to unusable originals, Switchcraft jacks and CTS pot. Mods to the circuit, I changed the volume pot to go after the first gain stage instead of coming right off the input jacks and I hooked up the input jacks to be a Fender style hi/lo configuration instead of both being the same. High is the top, low on bottom. Tubes are all high testing vintage-Sylvania JAN CHS 6SL7GT, Sylvania 6SN7GT, two Sylvania 6V6GTs and RCA 5Y3GT. I think all of the tubes but the 6SL7 are the original tubes. The 6V6s are 2mA apart in circuit. Here’s your chance to get a true classic! Video is of last one of these I did the same way for reference.
This item was found in an abandoned storage unit and is untested. Please see pictures for condition and contents. The projector is very cleam and has the power cord.
Vintage EICO HF-12 12-watt mono tube amplifier, previously modified from its original hi-fi configuration for apparent guitar/instrument amplifier use. This is an interesting restoration or further-conversion project for a tube guitar amplifier builder or vintage audio enthusiast. CURRENT CONFIGURATION – Original EICO HF-12 chassis, enclosure and transformers. Original four-position input selector removed and replaced with a front-mounted 1/4-inch input jack. Three remaining front controls: volume, bass and treble. Original rear audio inputs removed. Rear 1/4-inch speaker output jack added. Original speaker terminal strip remains, with altered connections. The 8-ohm terminal is presently unwired. Original decorative front faceplate is missing. Replacement Mallory electrolytic capacitors installed. Three-prong grounded-style power cord installed, but protective grounding has not been verified as satisfactory. Other previous wiring and component changes are visible. ELECTRICAL TESTING PERFORMED The amplifier has NOT been powered up or audio-tested. Resistance and continuity measurements were performed with a multimeter. Output transformer: – Primary end-to-end: approximately 341 ohms – Primary halves: approximately 187 and 154 ohms – Secondary G-4? : approximately 0.9 ohms – Secondary G-16? : approximately 1.3 ohms Power transformer: – Primary: approximately 40 ohms – Heater winding: approximately 0.4 ohms – High-voltage secondary: approximately 205 ohms total – High-voltage secondary halves: approximately 105 and 98 ohms No open windings were identified in the circuits measured. These are resistance/continuity measurements only and do not establish transformer performance under operating conditions. IMPORTANT ELECTRICAL CONDITION The three-prong power cord was checked for continuity between its grounding pin and the metal chassis. Meter lead resistance: approximately 0.2 ohms – Grounding pin to chassis: approximately 2.5-2.7 ohms The protective chassis-ground connection requires further inspection and verification. The power wiring, capacitors, previous modifications and overall electrical safety have not been fully evaluated. DO NOT CONNECT TO AC POWER UNTIL PROPERLY INSPECTED AND SERVICED BY A QUALIFIED TUBE-AMPLIFIER TECHNICIAN. RESTORATION POTENTIAL The EICO HF-12 originally used a push-pull EL84/6BQ5 output stage rated at 12 watts in its factory configuration. The existing instrument-style conversion offers an interesting starting point for a vintage guitar amplifier project. Actual instrument input characteristics, operating condition, output power and sound have not been verified. The amplifier could also be considered for restoration toward its original hi-fi configuration. This would require sourcing missing controls, connectors and faceplate components, tracing the wiring and making appropriate circuit repairs. Not represented as a working or electrically safe amplifier. Includes the amplifier and installed components as photographed. No additional accessories are represented as included. Please review the detailed photographs of the chassis, underside wiring, transformers, controls and connections.
