I have a friend that has a Packard Bell made amp. I believe it was from a stereo type amp in a console that was pulled and setup as a stand alone amp. I have a lot of sams photofacts so I probably have the info but need to figure out the model. Does anyone recognize it and know a model so I can lookup the photofact? Thanks in advance.
Does anyone recognize this Packard Bell?

^ Good call plus it's right there on the chassis DPA-10-1
Also there's a DPA-10 schem courtesy of @Tom Bavis in link below (post #11)

Willy,
check your amp to see if it uses 6AQ5 or 6BQ5 output tubes. I have a DPA10-3 which uses the 6BQ5 tubes as listed in the schematic posted by nerdorama. The link to the schematic posted by Dswankey uses the 6AQ5 output tubes.
I was racking my brain about a year ago when trying to measure voltages on mine and was looking at the schematic for the DPA10. Senior moment needless to say.

I don't recognized em but they are single ended looking like very nice amps. best to have a tech go through them before you plug them in. I bet once you get them back you will know what that single ended sweetness is about. check your local stores for cheap radio shack speakers from the 70's they should be pretty efficient speakers that if not damaged will sound just great for you...nice amp really nice amp. im going to see what i can find about them and post what i get....very lucky

Good catch!! I didn't notice that
yep I read on one DPA 10-1 they talk about them being EL84/6BQ5 tubes driver/splitter 7025 tubes look original markings on the EL-84's
Thanks for the replies. I had one number and it went back to a Packard Bell TV and I knew that wasn't it. This info will help as I will look for the dpa 10-1 and not the others. I have redone some of the Magnavox 9304 maybe, I can't remember the number for sure. I like to have a diagram on hand as you never know on these amps if something has been done wrong or if a resistor has burned up . I tell folks if you pull a amp out of a stereo to set up as a stand alone write down the actual model number of the device in case the diagram is needed later.

Good point! fortunately most of the manufacturers already labeled their chassis's
Some examples
Magnavox
RCA
Zenith
Motorola
The manufacturers do label the chassis but my question is what is the model number of the original stereo it came out of? If I knew that I could look it up in my sams photofacts. Only thing I was able to find to that number was a TV set. From other responses there seems to be a difference between the DPA-10-1 and DPA-10. So it would be nice to find a diagram that goes with this amp.

I see what you're saying, console pulls have become quite popular over the past many years so usually searching, for example "RCA RS-177" will usually point you to a link that has that exact schematic vis a vis threads here on AK or elsewhere.
In some cases you'll find info on sites like Radio Museum that will list the console model ID as seen here
TPR-8 Ch= RC-1193 Ch= RS-177 Radio RCA RCA Victor Co. |Radiomuseum.org
TPR-8 Ch= RC-1193 Ch= RS-177 Radio RCA RCA Victor Co. Inc.; New York NY, build 1959 ?, 1 pictures, 14 schematics, 20 tubes, United States of America
Magnavox was very good at ID'ing their console model #'s on the back of the unit, for example
Packard Bell console were not as prolific in manufacturing output so there's not that much info online as to what model # the consoles were.
One could also when searching find a treasure trove of info such as these long running dedicated threads
Calling All Motorola Consoles!!!
Anyone that has one, post up pics and any information you have on it. Thanks to TheRed1 (thank you Carter!), we have an excellent resource for Fisher consoles and a burgeoning database of Magnavox console information. But, so very little is known about these Moto's from the late 50's to mid...

DPA-10 has 6AQ5, DPA-10-2 has 6BQ5. I don't have the DPA-10-1 handy but I should have the Sams folder - 571-1.
I have the sams folders from about number 70 or so up to about year 1995 so I will look for it. Thanks!
