Acoustical Manufacturing Company (Quad)
405-2 Power Amplifier Original Brochure (two pages)

Mint condition, perfect and sold with Money-Back Guarantee.
Shipped within 1 day Priority Mail. Most of my manuals were acquired decades ago from a small bankrupt audio chain. Each store received manuals but only one or two locations serviced units. As a result, manuals untouched and unmarked. They were put in file cabinets or huge 3 ring binders. I'll ship internationally but it is expensive 
If domestic shipping fee is $10 insurance for full value is included.
Please read my feedback, I've worked very hard to earn it.
