Packard Bell Stereo Power Amplifier Model # DPA-30-3, (1963). This chassis is the power amplifier only, that I pulled from a large, oblong Packard Bell console AM/FM radio / phono combo set, when I was living in Colorado (These are rare in the East). The unit was slowly brought up on a Variac in August, 2019. Both channels sounded great, but due to the age, this unit should have its electrolytic and paper capacitors replaced. The A.C. line cord should be replace...d also, and I will include one for that purpose. All B+ readings are high, and the 8.2 K ohm, 2-watt resistor, ("R88"), runs way too hot. I replaced that, and the old one and a new spare will be included. B+ issues here make sense, as the B+ is no longer supplying the load for the now-gone pre-amplifier and radio receiver it once powered. So, restoration would require power supply modification in order to make this into a stand alone power amplifier. Google "Packard Bell DPA-30-3 Looking for some guidance" for more information on this subject.
The "octal"- like female jack in the top of the chassis , which resembles an octal tube socket, is actually a 9-pin socket, once used for the other components of the console. This is a hard plug to find today, so I'm including an 8-pin chassis octal socket and a new male octal plug so that you can change out the oddball 9 pin socket. This will make this port usable again. As always, such a unit should be fuse-protected, and fuses and a fuse holder will be supplied for your use. Two male, 2-pin speaker plugs will also be included.
The tubes:Five of the seven are the original ones, all marked "Packard Bell". None were actually made by Packard Bell. As was common in the day, most manufacturers would have tubes private labeled for them by the major tube manufacturers. The four EL84/6BQ5's are actually G.E. tubes, and the one 7025 is actually an RCA tube. The replaced Westinghouse 7025 is actually a G.E. 7025. The 5U4GB tube was missing, so I installed a new-in-box / new-old-stock RCA 5U4GB. All tubes tested good and were free of microphonics in the circuits.
Folder 11 of the Howard W. Sams Photofact set # 669, which covers the DPA-30-3, will be supplied.
As always, the unit is being sold "as-is", and should be restored for safe reliable use. The seller assumes no responsibility for possible failure, fire, injury or death resulting from the use of this unit, as unlikely as any of those cases would be.

This nice unit was hand crafted in California.
