### The Audio Board: www.theAudioBoard.com - The Search Tool for Used High-End Audio Equipment### For sale is a vintage, big and heavy, super-rare Pilotone AA-906 Tube Mono Power Amplifier, KT88/6550 Based, All tubes are vintage and all included except the two Genalex KT88 which I borrowed for testing only (they are listed separately). The potted transformers are big and the amp is really heavy. I provided some pictures to show the circuitry under the chassis. It appeared to be all original, no mods. No overheating or burning signs. I used a variac to ramp to 80 volts. The amp worked fine and produced music fine. Since this amp is very old, it may need services before daily use. At least, the new owner should have some professional to go over it before plugging in 120V. I am not liable for any damage to the amp if the new owner chooses to plug right in 120V. Physical condition is fair for the age, with wear, discoloration, and scratches as shown. Also the bottom plate does not look like original. More or less just a simple replacement to avoid touching the high voltage. The power cord is replaced with 3-prot plug. No cage. Ill ship worldwide. The amp is very heavy.

Sylvania 6550 Tetrode (KT88) Valve Tube Made In USA Used Tests Good See photos for condition. Tests good on Taylor Model 45C valve tester. Mutual conductance reading Gm 7.5 Tested as a KT88, as I dont have the exact input data for a 6550. 100% KT88 factory data in Taylor manual at Gm 11.0 Filament continuity, and mutual conductance test readings photographed respectively. UK shipping with MyHermes Tracked or Royal Mail. International shipping with Royal Mail International Tracked. I will combine postage on multiple valve orders. See my other listings!

These Tubes are in good overall condition and test strong on my simple B&K 666 tester. I have not performed any other testing. They were removed from a working Marshall amp to try out a different brand so I have no use for them anymore. Tubes are roughly 4 years old but do not have lots of hours of use. Thanks for looking.
