1969 National N-6899 Tube amplifier Head in Chicago for $350

The seller calls it a model 99 but it is actually a Valco National N-6899 and was the top of the line Amp and a brand new model during the last gasp of Valco before it's 1970 bankruptcy filing. It is about a sophisticated and powerfual an amp as they ever made. The seller describes it as a 50 watt amp but guess what - note that there are FOUR 6L6 tubes and two seperate output transformers - so it is a real DUAL CHANNEL 50 watt amp - like the Magnatone 480 Stereo amp. You shoould be able to drive two seperate cabinets with a split stereo signal with this baby and have headroom to spare.

I have here for sale one very special amplifier, yes indeed. If you are familiar with the National brand you know what I am talking about.
This amplifier was made basically on the same Sears Roebuck assembly line as the old Supro and Supras.
It is an antique('69). This doesn't effect its performance though. I had a grounded power cord and new tubes installed last year by Midwest Music Menders.
Other than that it is all original.
Features:
National Model 99. head.
50 watt all tube (6L6) power (12ax7) preamp.
Sweet analog tremolo
Tube reverb.
High/low inputs on two channels.
Built in power attenuator, i.e. Studio/auditorium setting

DON'T Let this one go!
