Excellent Quality Product

Very good preamp, good board with good components. It looks nice and above all the sound quality is very good. Try a good transistor amplifier or MOSFET IC. You will definitely like the sound quality.

Pros
  • REASONABLE DESIGN: Reasonable board layout, low noise, good component layout.
Cons
  • Nothing here

Terrible hum, fun soldering project.

Bought two of these. Both came with different capacitors, one with ceramic and electrolytic, the other with electrolytic only. Both produce an exceptional buzz. With the audio muted and just passing the audio through my amp it sounds fine, but none of the preamps I've bought can be used because they are so loud.

Pros
  • OP AMP IC SOCKET: This preamp adopts op amp IC connector, flexible, easy to upgrade, suitable for various purposes.
Cons
  • A small change

Incomplete due to lack of properly provided parts

So I started building this cool new amp I bought from Revain... and soon discovered... that while it can be tuned with a decent Ojo kit, it can't be built with the wrong parts, let alone because that it's completely missing there or at several intersections... oh, and if you take a closer look at the photos... the parts I need to complete the project aren't shown... is that my fault? For not interpreting a false fake ad that depicts something unfinished and therefore not worth the 8 I paidโ€ฆ

Pros
  • EXCELLENT PCB: This preamp uses FR-4 1.6mm double-sided PCB material, which has a long service life.
Cons
  • -

Incomplete due to lack of properly provided parts

So I started assembling this cool new amp I bought from Revain... and soon discovered... that while it can be customized with a decent Ojo kit, but can't cope with it parts supplied incorrectly, not to mention their complete lack of them at several joints... oh, and if you take a closer look at the photo... the parts I need to complete the project are not shown...is that my fault? For not interpreting a false fake ad that depicts something unfinished and therefore not worth the 8 I paid. Thankโ€ฆ

Pros
  • Durable finish
Cons
  • Damaged
