Vintage Tube Amp

Here is an awesome old 1948 Gibson GA-30 guitar amplifier. Looks like it has the original tubes. This amp has had a new handle added as well as the grill cloth was replaced at some point. I believe the speakers were replaced also. This amp currently works as is. Turns on and plays. The volume and tone knobs work properly. Now this being a 75+ year old amp, I will say that it will benefit from having an amp tech look over it and make sure all of the components are working properly. Right now it sounds pretty good with some slight hum when turned up loud. Has the original 2-prong cord that really should be replaced for safety also. With all that being said, this is a really solid 1948 Gibson GA-30 that has been used and taken care of for the last 75+ years. Should have a lot of life left if the new owner continues with proper maintenance.

Really cool vintage combo amp from the 60s.

For sale is a matching vintage Lafayette tube audio pair consisting of an LT-80A FM tuner and LA-55 mono integrated amplifier. Both units have been fully restored, serviced, and tested. They are operating properly and sound excellent. The LT-80A has strong FM sensitivity and receives weaker stations well, even with a very basic antenna. The AFC functions correctly and keeps stations locked in once the tuner has warmed up. As is typical with vintage tube FM equipment, there may be a small amount of warm-up drift with AFC switched off. The LA-55 amplifier plays clearly and strongly with no significant hum or operational issues. Controls, switches, and functions have been checked. Cosmetically, both pieces are in nice overall condition for their age. They present well as a matching set, though they are not museum-perfect and show some normal age-related wear. Please review the photos carefully for exact cosmetic condition. This is a great opportunity to own a restored matching Lafayette tube tuner and amplifier set that is ready to use, rather than an untested project.

Vintage Philco and MajesticType 45 vacuum tubes. Which is a celebrated directly heated power triode introduced in 1929. It was extensively utilized in the audio output stages of 1930s console radios and is highly sought after by modern audiophiles for its exceptionally clean and musical single-ended audio amplification. These were an estate find. According to historical data sheets like the Tung-Sol 45 Manual, the standard operating parameters include. Filament Voltage: 2.5 V (AC or DC). Filament Current: 1.5 A. Maximum Plate Voltage: 275 V. Average Plate Current: 36 mA. Amplification Factor (Gain): 3.5. Maximum Power Output: 1.6 to 2.0 Watts. The base features a standard UX-4 4-pin arrangement. When looking directly at the bottom of the base with the two larger pins pointing toward you. Filament Pins: The two larger/thicker pins (Pins 1 and 4) carry the 2.5V filament supply. Plate Pin: One of the thinner pins (typically Pin 2) connects to the high-voltage anode. Grid Pin: The remaining thin pin (typically Pin 3) serves as the signal input grid. The handwritten text “FIL OK” on the glass bulb indicates that the filament has been tested for electrical continuity and is not broken. I didn’t test it, but I believe it’s in good working condition. Please view photos for more details.
