That happened to me also... I forgot

I corrected it on the second channel.

A build guide will be welcome.

1st.... place all resistors.
1st.... place all NPN
2nd... place all PNP
Be carefull to keep low riding ones beneath the heatsink
3rd.... place diodes and small caps and light emiting diodes (measure all diodes before implanting)
4th.... trimmers
5th.... opamps
6th.... small EL
7th.... heatsink with power trannies
8th.... big EL

This is only a first approach.. should be finetuned with all intervenients opinions and best practices.

PS: Remenber there is need to GND connection in the riaa case for the arm GND wire (unless you use a rega or other thing that uses left channel gnd as arm gnd)

After Test-Clamping with the actual cooler,
one has to observe how short is usefull.
If one shortens to much, the clamps are useless.

For the big ones on cooler
I first fitted the transistors to cooler before welding

One may start form sides or middle fit first one nice and square twiddle in place position the second one take out and clamp repeat till lot is in and then weld

Or, found it after, weld in place transistors and then use magic tool like in picture to clamp

IMO this is the most difficult part of build so take your time as clamps are a pain to get off.

I prefer to lay the power trannies on the heatsink, then fix them with the springs, then point them into the holes, fix the heatsink and finally solder everything in place.
