Seriously, cloning this would be a waste. The sound of this amp is dictated by the chip being used as ultimately it is the comparator of input vs feedback + it's foibles.
There are far better chips available today including drop in replacements. Thie LF353 was a lower form of LF357 which had a strange 'popping bubbles' sound but, hey, that's my interpretation!
There are any number of superior chip to build an amp around today.

Perhaps you did not see the "for experimental use ".
An OPA2604 is a better sounding, drop in for the old LF series.
The designer likes the AD823 better, and gives tips on how to select for ±20V use.
I would like to see a hexfet version, APT makes some huge N-ch that look interesting.

Hi Odysseyvn, All
thanks for the pics.
I do not see the op-amp in your board (I see only the
little holes). May be the four devices are a discrete
replacement of the LF412.
If so, I am very curious about how your Amp sounds.
And, I admit it, I am also a little envious.
Try asking to J.Bongiorno in the SAE_Talk forum.
Hi ACD,
if you'll make a PCB, I'll be happy to discuss with you and other guys interested in the subject, about
some improvements that work on the paper.
Do you intend to keep the original board measures ? If so, someone could be interested to purchase a couple of PCB.
bye
Federico
