their respective holes with ease. The most unforgiving parts are switches
with two or more rows of tabs, such as DPDT switches. These must be
aligned correctly.</font></span></div>

do this for all panel components – pots, jacks, switches, and LEDs. I’ll tack
solder just one lead so I can get the panel on and everything aligned. Typically
the pots aren’t quite at the right height and this puts stress on the phenolic
which can crack. Once the panel is on I reflow the jacks, pots, and
switches. Sometimes I can hear a “pop” as the pot lead relaxes and it adjusts to
the correct height. I do the LEDs as you described.<u></u><u></u></span></p>

once sent me a Buchla 248 with all the switches soldered on with no panel. Of
course none of them lined up and it is hard to remove the solder completely so
you can realign. I ended up having to redrill all 35 switch holes oversize and
file some to fit.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:blue;font-size:10pt">LEDs can
also be a challenge to solder into panel PCBs as they might not be at the
correct height for poking through the panel. The best way to install LEDs
is to first install all of the other components, then stuff the LED leads
into the PCB loosely, then actually attach the panel (with at least a few
nuts) and push the LEDs into their panel holes while the panel sits
upsidedown on the bench. In this way, all the LEDs are at the correct
height. I have also made LED jigs from scraps of PCB material (of which I
have many pounds!) that bridge two adjacent components.</span><span style="color:rgb(31,73,125)"><u></u><u></u></span></p></div></div></div></div>
