Up for sale is a brochure put out by Dynaco featuring the Mark VI Power Amplifier.  Measures 8 1/2" x 11".  Very good condition, shows a little wear.  This is a two-sided single sheet.  Reverse side features specifications.  This is an original document.

I pack for safe shipment.

I charge a shipping fee so those that want to purchase more than one item can save on combined shipping.
