With its sleek and durable design, it is a must-have for any audiophile. This power meter is made by Realistic, a trusted brand in the audio equipment industry. It is compatible with a wide range of audio devices and is perfect for both beginners and professionals. Whether you're a DJ, musician, or simply a lover of great sound, the Realistic Audio Power Meter APM-500 Model 42-2107 is the perfect addition to your collection.

UPDATE: The original instruction manual is also included, and the manual includes the schematic! I purchased this Realistic APM-300 audio power meter new in the mid 80s, and it has seen little use since the late 80s. I occasionally wake it up to check that it still works, and then I put back on the shelf to wait until the next time. This one-owner unit is in better cosmetic condition than most of the units I see being currently offered. While searching the web for relevant information, I came across a screenshot of the page from the 1982 Radio Shack catalog for the APM-300. The price, in 1982 dollars, was $49.95. Just for grins, I checked what that would be in 2024 dollars: $155.85 ! I will soon post a link to a video where I check out the operation of this power meter. Please take a look at the photos and video carefully, and make sure to ask any questions before buying as this item is sold as-is. Any items shown in the photos or video besides the power meter are not included. I will carefully pack this to withstand the ordinary an expected rigors of shipping.

Good and Working
