Rare Homebrew Linear Amplifier 4cx250b L@@K:
$30

sale is for a Professional made ROOSTER built 4cx250b linear amplifier i received from my grandfather who passed away. It has 3 brand new TAYLOR 250b tubes. Amplifier was recently service and has new capacitors,chokes and tubes. This linear is built very nice and is in very good condition to be 21yrs old. Technician also added extra fan on top to pull air out, just mounted on top i did not want him to cut anything. This amplifier has a whole lot of swing. Runs very very smooth and quiet! Has Bias control, Tune, Load and Input controls. CRYSTAL CLEAR AUDIO!

Amplifier has a bias control knob located on far left. It contains stages 1-6. Each stage let you produce different wattage's for to type of drive power you will need. VERY CONVENIENT.

All test were done on bird 43 using 4w dk swing 10w. Was told per tech amplifier could take a slight more of drive. NEVER PEAK TESTED ONLY RMS TEST ONLY!
BIG SWING
1st stage -80w swing 400w
2nd -120w swing 450w
3rd-160w swing 500w
4th-220w-swing 600w
5th-400w-swing 600w
6th-600w-swing 850wetc.... depending on your radio etc... With the right radio and the Bias switch on 6 you can Deadkey low 40-70watts depending on drive input and swing 775.

This amplifier is a beauty and i have not been able to even find one to compare it to. It is very very nice. It does power up and work great without any flaws. I Really hate to see this amplifier go however i am no operator nor intend to be an operator.

READ MY response! I HAVE SOLD MANY HAM/RADIO ITEMS ON SO offer WITH CONFIDENCE. ITEM WILL MEET DESCRIPTION AND WILL NOT BE DOA!

Again amplifier will produce 850 bird watts but runs comfortably around 450w-775w continous power. CRYSTAL CLEAR AUDIO AMPLIFIER! This is one bad Linear Dont miss this great opportunity to own this rare vintage linear.

Very Heavy shipping 55.00 insured double boxed packed well. WILL NOT BE DOA! LOCAL PICKUP ALSO AVAIL

USA ONLY!!!!!

NO RETURNS ACCEPTED UNLESS DOA!!!!
