aha

*banging my head* Cviller's F5X. there is no F5x boards from him

i did not get that the first time

and yes. like the F5c boards. only with more space between the 2 inner fets.

How much lead spacing is there for the 'small' resistors? It would be nice to fit a PRP or dale RN60, as those are about as big as most 'audiophile' resistors. Some people will want to use them.

Great to see the pair of J74 - could you put a pot at R7 as a variable resistor?

If possible, the 0v traces should be bigger, and another wire pad added near the input to connect signal ground, psu ground and speaker ground at one place. See the F4 or F5 pcb in the store for an example.

Thank you so very much for your efforts!

Lead spacing for small resistor 10mm. I add pot for R7 and wire pad.
For long board, i'll try to make one.

But still the spacing for the UMS...

AudioSan · 5th December 2012, 02:14 AM

yes 6L6. say 120mm between the inner fets. thats fine for UMS

and then 40mm to the outher fets

The intent of this board is that it will become the one sold in the DIYaudio store -- Hence the UMS and a few other tweaks.

A question for those smarter than me - (of whom there are many!)

?Does the entire amp see ground through R2??? It looks that way on the schematic, and on this board...

Regardless, the trace between the GND pads and R2 need to be thicker.

And if you could entertain another request, I would love to see an LED on each rail, so you can see at a glance that the amp board is powered correctly.

Add 3 LED, V- to GND, V+ to GND, V+ to V-. Add alt Cap for C1, 22mm spacing.

Which one do you Prefer, Long board or square board?

Wow! That is looking great!

The long board is ideal for this amp.
