1972 Ampeg B-15 S Portaflex Bass Amp - Rebuilt!

Up for sale is this beautiful vintage Portaflex. Unlike every other Portaflex amp, this uses a solid state rectifier, doubling the output wattage to 60 watts unlike the 30 watt B15 making it suitable for gigging and studio use. It has been completely rebuilt, and it sounds absolutely sexy. It has the Altec 421 15" driver which was an upgrade from the factory over the stock CTS speaker. It has the original power and output transformers, original tone stack and pots. This amp is an effing tone monster, and I hate to sell it, but oh the life of the self-employed musician :/

Here is a list of the upgrades/repairs:

New JJ electrolytic power supply capacitors 
New bias section (electro/flyback diode)
New bypass capacitors (Sprague Orange Drop/Mallory 150)
New higher capacity grid resistors
New tube sockets
New power cable
New JJ 7027 power tubes, still have the original and functional RCA 7027 power tubes (included)
NOS GE 12AX7 preamp tube in channel 1, NOS GE 12AU7 in channel 2 for a softer low gain ch.
New JJ 12DW7 signal inverter tube
NOS RCA 12AU7 in EQ section
New lid latches (included but not installed)

All original parts that were replaced have been kept as well (included.) The tolex is a little rough but can be replaced. I wanted to keep it original looking. The grille cloth is in great shape.
