This is a pre-WW2 vintage Vacuum tube audio audio amplifier made by Presto Recording Corp. The model 88-A was the first hi power model built exclusively for use in disk recording. This has 4 X 807 vacuum tubes in push pull output.
This amplifier is in fair condition with rust and missing paint. There is one vacuum tube missing. This is a very hard to find pre-WW2 Presto Recording Corp amplifier. This would be a very great restoration project.I have not tested this, it is original as found. This item is in the category "Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps". The seller is "navships" and is located in this country: US.
