Thanks Peter, got mine up and running .
A couple of questions before I go any further. On the mods pdf, what is the jumper from 5A to 5B for, does it bypass a transistor?
Second question, when you use a two legged Oscillator, do you need to add caps to the centre, B position?
Thanks again..
PS, I have no idea were to put the display and buttons yet.

With the crystal, in most cases the additional caps are not needed. I tried it with the caps (10pF or so), but they affected the sonics in a way I didn't like:

Depending on the crystal type, without the caps some people experienced skipping or problems with TOC read out. In such cases I would recommend adding 3 twisted wires which will produce required capacitance without the signature of regular caps:

The 5A to 5B wire is for PS connection right after Q902 to the rest of the circuit; I cut some traces when I was experimenting with different supply setups and decided to connect it this way afterwards. It is not really needed, but maybe beneficial in some ways.

Hey Peter,
I like the "gimmick" cap you came up with for the crystal. I ordered the same type you are using for mine. I take it you have not encountered this problem with the citizen crystals you are using.

I will post pictures of the RCEZ32 boardset once I receive the unit, hopefully disassembly will confirm that the boards are the same or utilize the same chipset.

Kevin

No problems with Citizen crystal.

Based on USPS tracking number I might have my boombox by Saturday, just left the Springfield MA facility so it should be in Boston today and Quincy tomorrow. I'm keeping my fingers crossed..

I'll post the score once I get the unit apart, hopefully this is another unit people can purchase as a donor for the mechanism and board sets.

I should say I agree with Kevin,
