What is a JLH AMP?
The JLH amp – prelude. The JLH-amp, or more correctly John Linsley-Hood’s class A amplifier, is probably one of the most well-known designs in DIY audio. The original version was published in 1969, but that’s a little before my time.
Where can I find information about Linsley-Hood amplifiers?
The first factor is Geoff Moss’s excellent “The Class A Amplifier Site” (TCAAS) resource, now hosted by Rod Elliot of ESP, that started around 10 years ago (ugh, how time flies!). The site collects a lot of information about Linsley-Hood designs as well as other well-known Class A designs from the likes of Jean Hiraga and Musical Fidelity.

Which JLH for esl57’s?
The little 10W JLH worked well with the ESL57s, albeit with some occasional clipping on louder passages, and Nick felt that a higher current version would best meet his needs. The ESL57 is a difficult load to drive in that it is capacitive and its impedance drops to a low of around 2ohm at 15kHz.
