On the last page it also says how to wire the speaker.

I'm looking forward to the finished amp :0)

Hi Gary,
Check out this link
http://pedalparts.co.uk/wp-content/uploads/2012/12/rubycricket.pdf
It shows how to wire the power and how they have the pots labelled 1 2 3. I guess you just wire the pot lug to the corresponding hole number on the pcb.
From the info you have the ruby version and so you don't have a tone pot to solder.

Ok Alan and David my saviours attached are photos of the curcuit board I have put it all together correctly "I think" but I dont understand the plans as they dont show where the wires go  I have attached a photo of the board and the bits left , I would be obliged if someone  could do me a drawing of where the wires go if its not a problem

I have just hacked a Roberts R404 radio (1965-68)  And it seems lacking in power. My previous hack , a Roberts R606-MB is a total power house running from 6 c size batts. The 404 has 2 pp9 batts ( 18v) and is much quieter! It does use a 25 ohm speaker tho and the components are an older vintage. I came across the 404 without the radio part working.

Any one notice big differences in power output? The 606 is maybe 1970ish so different parts.

Anyone else seen this cheap amp module? http://www.ebay.co.uk/itm/Mini-1pcs-LM386-Audio-Amplifier-Module-/3... quite interesting eh?

Hi Gary,

Having a look around the www

From here http://forums.parallax.com/showthread.php/96165-Identifying-polyest... their wisdom is that it stands for 0.1microfarads

0.1microfarads = 100nanofarads which is C4 on your contents list.
