The 918 opamp is my favourite of all the discrete options I've tried, and they are the heart of all 607 products. With a tightly matched input transistor pair, high quality metal film resistors and C0G capacitors, they make everything they amplify sound fantastic.

Had a Yamaha Rev 5 in for some restoration. The first picture is the before, the next is the repair. The meter is running again. Holy corrosion though, if I had to guess I would say this one had Coke spilled on it. Recapped it while I was in there. Likely going to upgrade some of the 4558 opamps, it's quite a hissy unit, but a very cool device overall.

Prepping some input transformers.

High nickel, custom wound, flat response, what more could you ask for.

Doing some burn in on the two 827s on the right against the benchmark units on the left. These two, and 4 others passed all the tests and are available through the website, or you can DM for more details or to order.

As we continue through the creation of the 827, we arrive at final assembly and the start of QA. All done under the watchful eye of Poe.

Gain and attenuation switch boards for the 827. Each contain a custom 41 detent gain pot and a Grayhill 6 position attenuator switch. Only the highest quality components are used here.
