Welcome fellow collectors and vintage car audio enthusiasts!

This listing is for one original owner’s manual for the PQ40 PowerPlate amplifier, from the heyday of a/d/s/ while they were still located in Woburn MA (based on the company info on the back cover). This is a factory-printed manual with stapled spine as shown. The PH30 is a very complex amplifier and anyone installing one or setting up the crossovers will want to have this guide in front of them. A total of three manuals are available at the time of this listing, you can select the quantity desired when you place your bid. 

Please check my listings for other original manuals, brochures and assorted audio literature.

Buyers, please note my shipping practices as follows:

• This auction is set up to reflect free domestic shipping, with no handling charges. 
• I make every effort to find and use the lowest cost shipping method appropriate for your item, and refund surplus shipping paid whenever possible.
• Please remember that selecting the lowest cost shipping method also results in the slowest delivery - please do not leave low detailed seller ratings because of this fact! If you need the item faster, Priority Mail is a better choice.
• Please contact me if the shipping method you want is not offered in the listing. If that service is available for the particular item, I will revise & resend the invoice.
• I am not a full-time eBay merchant, but an experienced vintage audio enthusiast. I put many hours into supporting my customers and listings on eBay but am fitting all of that around a very heavy full-time work schedule. However, I always do my best to ship within the guidelines posted in my listings.
• In the case of larger items shipped overseas, USPS Priority is currently the lowest cost service available. DHL & UPS are much, much higher. I will use First Class Mail International where possible but it has a weight cut-off of 4 lbs.
• I use recycled packaging materials when I can, because I believe it is the environmentally sound thing to do.
• I also use new USPS Priority & other packaging materials to supplement the recycled materials where appropriate.
• I’m always very careful to make sure the item being shipped is properly protected regardless of the type of packing materials used.
• Please note that 4 star ratings while seemingly above average do not qualify me as an excellent seller by eBay's standards. If you feel that you can’t leave 5 star ratings in any of the four categories, please contact me to resolve whatever issue has caused you to feel that way. I am committed to meeting the highest customer service standards.

Please keep the above in mind when you leave feedback. If you feel you cannot leave 5 star Detailed Seller Ratings, please contact me so I can resolve whatever issue you may have. Thank you for viewing my listing!
