Hi Erik,

I was just wondering; how many hands do you have?

In other words who took the picture? You are holding the PCB with both hands aren't you


Nice work BTW!


Best regards,

Audiofanatic

You are certainly not an avid reader......

The one holding the board is the artist who soldered it...go figure

If You investigate the 317 regs you will find they are the wrong way round. Eg the silk screen on the clock pcb is wrong

LM317 pinout

I think there are alot of these clocks out there where the regs are the wrong way round.

I think your oscillator must be correct or it wouldn't work at-all.

well I realise I arrived rather late to this particular party - but my EZ51 was relinquished of it's transport and display and is now fixed to the usual development board!

Click the image to open in full size.

had almost enough bits for an 8v power supply handy - apart from an 8v reg - so I dropped the ref leg of a 7805 down through 5 diodes to give me the extra 3V!! - I know, bit gash but it was just a lash up to get it going

Click the image to open in full size.

it's currently feeding a cheap 24bit DAC (partially modded!) - still in it's cardboard box!

so far the only mods to the transport are a couple of ultra fast diodes, a proper 7808 and a couple of 1000uF caps. The combination is fed through the aux input of my Linn Classik and beats the pants off the Classik's own player - in EVERY dept. The pair are just amazing together. I'm so glad I saw this thread and really can't thank all the previous contributors enough.

My BG's arrived a day or so ago so I reckon I'll be attacking the circuit board this weekend - at the moment I don't want to unplug it to start modding - it's compelling listening - love it.

oops - forgot to say - the remainder of the JVC is back in the 51's case - the cassette and tuner work independantly still.

I fitted a couple of RCA sockets and a 3.5mm jack to the now redundant CD inputs to the amp - so the boom box is now my bench amp come workshop radio.

nothing wasted!!! - top stuff!!
