Very nice offer, I have just ordered 2 x JLH 2005 kits.

I also wanted to order the power supply kit (with transistors + capacitors...amazing offer) but for some reason it has to be ordered separately. If you could offer combine shipping I would of also order 1 power supply kit. If you could offer combine shipping, your client could order 1 power supply kit with 2 x JLH 2005 kit and have everything to start their project.

Will combine shipping offer soon ?

p.s. You can PM me if you need some info about my order.

Looking forward to receiving the kits and starting building :D

JLH designed and used a regulated power supply in 1969 for it but I see there is an updated version as mentioned above. This amp was highly thought of in the pages of EW/WW mag by many ADEs .Its simple to build and sounds good.

For anyone still looking for PCBs for this amplifier, could try "amplifi_07" on Ebay. I have no monetary interest in this recommendation, just bought 4 pieces off him (Michael Bernard of the Czech Republic), very reasonable, the PCB is beautifully laid out and best of all, includes a Capacitance Multiplier on board thus making assembly very simple, just 20V AC in. His board recommends MJL21194 as output transistors (possibly because the plastic T0-264 package mount direct onto a flat back heatsink) but I am wary of possible hum or oscillation so I am sticking to the trusted and excellent MJ15003 using PCB terminal connectors and T03 sockets. I am looking forward to completing a pair, although I already have a pair of the Higher Power version in mono block construction. Good luck!!
