Works as it should Time Owned: more than 12 months.
I purchased the Low Profile Rock Topper Amp with the LMB CR-425 Case in April 2015 and just completed it last month (April 2022).
The manual used is for the Tuna Topper ][+ Version 5 PCB (Aug 2016).

I held back because there were many changes made with addendums, notes, etc. I received assistance from Rex, W1REX and Chuck W5USJ.
Rex helped a couple of times via email. One, I wasn’t getting 4.7V at the bottom of R2…The Zener Diode ZD1, needed resoldering it’s ground connection. Chuck, W5USJ provided an email, plus attached drawing with a much more elegant way to power the LED with the + and GND either side of C13 and use a couple of pads on the back of the board for the Pwr Jack & Pwr SW.

I decided to make a 8 ½ X 11 copy of the board and mark the components off as added. Made things a bit easier.

Good quality components & board but make sure you read the documentation thoroughly and re read everything and make notes on how you will proceed, the documents can be a bit confusing.
