Here are some pictures of my Sony TA-2650 recap project. I've always liked these amps, the brushed aluminium faceplate just looks SO classy. The little 2650 gets no respect, compared to the VFET models, and it probably also gets overlooked because it's narrower than the 3650. But it's rated at 43 wpc into 8 ohms, has two tape inputs (including useful jacks on the front you can connect an MP3 player two), as well as an interesting "presence" control in addition to the usual loudness.
Here is a view inside. Notice, there are a LOT of low-leakage orange Elna capacitors in here, more than I've seen in a lot of other amps. Notice as well the dual caps in one can in the power supply. The front and rear panels tilt to make servicing easier, but you still have to remove the boards to get to the solder side.
Close-ups of the power amp board...
...and the control amp and function switch board. Just look at that Alps volume control.
I carefully desoldered the volume control pot so I could open it up for cleaning. Here's a little photo montage of it.
Control board recapped.
Function board recapped.
These two smaller caps are going to replace this one big one.
