Sjöström Audio - QRP01 The Gainclone - high performance power amplifier. A LM3886 from National Semiconductor.
The heart of a Gainclone. It took a while to understand what "GC" was, or Gainclone. What a name! A couple of IC's (LM3875, LM3876 and LM3886) from National Semiconductor are very popular in the DIY community. The LM3886 is the most powerful and delivers around 68 watts and peak power of 120 watts. Click on the pictures to get a larger view. I have designed a Gainclone and it's universal in most respects? DeLuxe version: Inverting or non-inverting LM3886, can be chosenInverting or non-inverting input buffer, with or without gain, can be chosenFeedback network which can satisfy everyone, full gain at DC or gain of 1 using a capacitor in the feedbackWith or without DC-servo for both inverting or non-inverting LM3886, can be chosenOutput filter, L//R, small handwound inductor plus a resistor.Inputfilter, lowpass and also highpass to block incoming DC-signals.

Time To Get Theoretical I know some this will be a little heavy going for some, but don't be put off, the conclusions are interesting.
There are still quite a few things that have influenced the development of this project, both the commercial JLTi and these two DIY versions – primarily the Tube version. Some may ask, what is the differences between the JLTi and the DIY (Tubed) version? For a start, the Tube Buffer in the JLTi is much more enhanced, the so-called SLCF enhancement. For a discussion of the SLCF and other good things, may I again refer you to my on-line essay: Tubes & the Gainclones Also this enhanced Tube Buffer needs higher voltages to work comfortably. If you wish to regulate your Tube, then by all means go ahead. Gazing Into The Dark What follows may be theory and attempting to gaze into the dark.
