I returned to DIY electronics in 2009 after a 20 year pause by building a few kits to get in shape. This blog is for me to keep track of my progress.
Krell KSA-5 clone
When I saw the discussions of KSA-5 headphone amplifier on head-case.org and on this forum, I thought it may be a nice use for the bag of 1000uF capacitors I had at the time. This was the main motivation for putting this Krell KSA-5 clone together.
The main challenge was to drill the front panel. The 10mm aluminum panel that came with the enclosure is easy to work with, but I wanted it to be pretty and asked the people at Modushop to CNC it for me.
Although it works ok, I think it is not a very good power amplifier for loudspeakers. As a headphone amplifier, it is no match for my Musical Fidelity X-CANv8.

I wonder how it will perform as a line preampPosted 24th February 2017 at 02:35 PM by idir

KSA-5 is a power amplifier that can drive speakers. I think using it as a line stage is an overkill unless your power amp is a gain-less buffer such as Firstwatt F4. Even then I guess you could live without the power transistors (Q23-Q26) and perhaps with fewer pairs of the driver transistors (Q15-Q22). Personally, I would rather use the BA-3 front end as a line stage, not the KSA-5.Posted 26th February 2017 at 08:48 AM by alexcp
