Custom 20W 6v6PP Amplifier  $429.99

Item - BHA20
This Excellent 20 Watt Custom Harp Amplifier has been Custom Built (by Jerry Kroker of Kroker Amps) into a Vintage Bell & Howell “Filmosound” Speaker Cabinet which measures 17” tall, 16” wide, 10 1/2” deep and with the amplifier inside weighs 25 pounds. The sturdy cabinet is in good cosmetic condition but does show signs of it's age and has some off color paint on the back cover where it looks like a repair was made to the cabinet. The inside of the cabinet is also in good condition and is lined with a felt material which is intact and in good shape. The back cover has a hinge along one side and a pair of heavy duty clasps on the opposite side which keep the cabinet securely closed when playing or in transit.
The original B&H speaker has been replaced with a 12” Weber Signature Series Model 12F-S which has a smooth cone and delivers a nice punchy output with excellent breakup for Harp. The amp chassis was designed and built specifically for this cabinet and is laid out very nicely. The Power Transformer is perfect to power this 20W amplifier and the Variable Load Output Transformer is designed to automatically adjust to any speaker load from 4 to 16 Ohms so you can easily plug in an external speaker if you need to.
The amplifier has a pair of 6C4 Preamp Tubes, a 12AX7 2nd stage/PI Tube, a pair of JJ Brand 6V6 Power Tubes and a 5AR4 Rectifier Tube. On the Instrument Panel from left to right are High Gain Input Jack, Low Gain Input Jack, Pre Amp Volume Control, Tone Control, Post Amp Volume Control, Power Light, 2 Speaker Jacks, Power Switch and Fuse Holder.
The amplifier is very easy to setup for virtually any microphone by simply adjusting the Pre Amp VC and Tone Control to get the desired sound and then simply adjust the Post Amp VC to set the output volume for the venue. The 2 volume controls allow you to setup the amp for either clean or dirty playing with just a couple of simple changes (the higher the preamp volume level is set the dirtier the tone will be). This is a very versatile amplifier with excellent tone and 20 Watts of Tube Power which is enough for most small venues. You can easily add a second speaker for a bit more volume and tonality (just plug and play).
The amplifier has less than 10 hours actual play time on it since it was built in 2011.
