meng el84 integrtated amp FM antenna location

I have a degree in computer engineering, so I promise you I know what a fried resistor smells like. The circuit board is a two sided deal and all the resistors or on the back side.
I'm a little reluctant to view the underside. There is a lot of wiring to be disturbed. If I send it back, I don't want them to see I've been rooting around. The tubes all light up
and, from what I can see, everything looks fine. What's your best guess; transformer ?

Probably something as simple as a hidden broken connection in the signal path. Possibly within one of the cheap elements they use. Given the plethora of wiring, a poorly executed solder joint, or broken snapin connector termination could be the culprit. I would guess that an internal transformer failure would be unlikely in the absence of any mistake you may have made. I am not an engineer of any kind just an MD with a half baked dillatente's knowledge of electronics from playing, breaking and dissecting equipment for 35 years. So take the value o my free advice for what you paid for it.

Since your an MD, I've got this pain in my side. JUST KIDDING!
Many times the practical side is better than the scholastic Thanks for the help

You were right. This unit is pretty poor quality. So far found 2 poor solder connections. Looking into Prima Luna, a little out of my price range, but may find something.
Thanks, Again
