The purr1n theme AliExpress / eBay JL Hood 1969 Class A Amp excited me. I decided to make my own "JLH-69" Ordered coolers. They arrived today. Had to order at 8 amps. Fewer they did not sell. Each cooler dissipates 70 watts of heat. I changed the amplifier circuit a little. The speakers are not connected to a common wire. Such inclusion of speakers will allow to reduce a background and to improve symmetry. But this of course need to inspect. I made an approximate design and made drawings for laser cutting and manufacturing of body parts. Two design options. The design is classic. Nothing extra. First "DOCENT" The second "PROFESSOR" Front mounted VU meters the back of the amplifier is the same in two versions. Now I start to make PCB. After the holidays in China will order a few boards factory quality.
