Picture of prototype 8060A from my collection. You can see the MAC chip in a ceramic DIP with a glued on top, dated Jan 6 1983. The TRMS chip is in a socket. If I remember properly, I used this 8060A to test the TRMS chips for performance and consistency with the selected components. Just to the left of the MAC chip, you can see a blue ceramic cap that is kludged with a long lead wire. In the lower left hand side you can see an LM334 and two kludged in resistors in place of the constant current diode that was and is the final design. I think I was experimenting with using more current than the FET based CC diode. Also notable is one more Tantalum Caps than in the final design. You can see it just above the pot next to the TRMS chip. This is now a 100uF/6.3V Alum. The tantalum cap next to the Piezo is a larger size than the final design. |

Just speaking for myself, though I suspect I might find some agreement here, I think the design envelope is open again. Should you see fit to make any...improvements...well, it IS your design. No bean counters here! |

Thanks for the pic. , the big question is ....... Are there any bodge wires on the bottom side ?. :D --- Quote from: WastelandTek on August 14, 2017, 01:41:02 am ---Just speaking for myself, though I suspect I might find some agreement here, I think the design envelope is open again.

Just for the record I don't own one ........yet ............. , but seeing the shiny one of fungus's ......hmm nice. |
