An early 70s Ampeg V4. These are tough to date exactlybut I can reliably say its between 71-73. Early Magnavox era. Perfectly working, Just serviced with new filter capacitors to ensure reliable power supply operation. Features a set of vintage GE 6L6GC power tubes. These are valuable rugged old glass. All testing well. In this amplifier 6L6GC and 7027A can be used interchangeably with only a simple rebias necessary. Power tubes have been properly biased. The preamp tubes are mostly original vintage Magnavox, RCA's. One 12DW7 is made in Gt. Britain so it could be a Mullard. The 12AX7A for the reverb was replaced. They all sound excellent, nice and quiet noise wise with lush vintage tone. Reverb is working great and I believe that tank is original. The power indicator lamp bulb and tail resistor was replaced internally but the original outer lens was retained in order to keep it as original visually as possible. Grounded 3 prong power cable also added for safety. Original transformers. This amp sounds amazing, nice warm and responsive tone! Please ask any questions you may have prior to purchase. I'll be glad to help you out. Cash pickup available. Will ship via UPS. This amp is HEAVY!! Will pack like a tank to ensure safe transit. Worldwide buyers are welcome! I've been safely shipping vintage Ampegs to Europe and other places around the world! Most sellers won't even consider this! Ill be happy to facilitate a safe delivery. It
