 Pair 4-1000 Amp Homebrew with Spare Tube  
Beast of an amp, if you want power, here it is. Hate to sell it, but health has changed and doctors like money. Honestly one very stout built amp, running a pair of 4-1000's. If you know the tubes, they are capable of running about 2kw with 100 watts of drive. Will not work the voice portion of 10 meters for obvious reasons. Runs on 220v. Has a QSK circuit built in. 19" Rack mount is not included in the sale.
This is obviously a pickup only here at my QTH in NW Indiana, and would need enough manpower to load it. I am not able to lift it. If the timing is right might be able to have at least one person here to help with loading. There are no stairs so that is a plus. Happy to answer any questions you may have.
Price is $3500 with the spare tube and chimney included. Will not separate. Happy to demonstrate the unit before purchase.
