Denon PMA-1090G
Documentation on the Denon PMA-1090G is thin. What survives comes mostly from collector listings and forum posts, not official literature. The record does show an integrated stereo amplifier, and the "G" in the name almost certainly refers to the gold finish, which appears to be the defining feature of this variant. One Russian listing calls it the "flagship DENON PMA 1090G (GOLD)," and an eBay title calls it a "Gold MOS Class" amplifier.
The most useful context is a drive2.ru post that places the PMA-1090G in a specific Denon family. By year of release, it sits with the PMA-560, PMA-860, PMA-1060, and PMA-1560. The same source calls the 1090G a "clone" of the PMA-1560. By dimensions, it is reportedly closest to the PMA-560, and the author speculates that its specifications likely follow that model. That is an educated guess, not a documented fact.
Beyond that, the verified details are sparse. A Japanese audio database (audio.misway.com) lists power consumption at 250W and notes AC100V, 50Hz/60Hz operation. A YouTube review title suggests Class A operation, and a Russian video review is titled "Denon pma-1090G Quite good." One Avito listing asks 110,000 ₽ for a unit. An eBay listing for an AC100V working unit is currently marked sold out. No service manual for this specific model shows up in the usual databases. Searches only turn up manuals for other Denon models.
No power output, frequency response, THD, or dimensions with actual values have been documented for the PMA-1090G.
