* CA3046 can still be got for some suppliers such as Banzai, Das Musikding, Small Bear and some 
reputable Ebay sellers. 

http://dsmcz.com/prestashop/en/

 sell UL1111 for only £1.53, they are 

functionally identical to CA3046. Alfa Rpar will shortly be releasing a CA3046 clone. The PCB also 
includes pads for SMD LM3046. 
 
** I prefer the Song Heui tall trimmers because they have a longer shaft and a white notch. 
 
*** If you can

’

t get C50K, use B50K instead
