andy67 Posted March 29, 2016 Share Posted March 29, 2016 Hi ye all Hopefully someone will know the answer to my question. As per the [url="http://ashdownmusic.com/products/1/Bass-Amplification/1/Valve/11/Little-Bastard-/"]Ashdown[/url] website, the LB30 has a 12ax7 (83) and an 12au7 (82) however, when checking how to disassemble it to change the valves, it appears as though there maybe 3 preamp valves?? See link to image below: https://ampstack.files.wordpress.com/2013/04/dscf1465.jpg Can any one shed light on this as I've ordered the 83 and 82 as well as a matched set of EL84s - all electro-harmonix? Feels like I've missed something now cheers all Andy Quote Link to comment Share on other sites More sharing options...

andy67 Posted April 3, 2016 Author Share Posted April 3, 2016 Once opened all became clear. It's another 12ax7. Quote Link to comment Share on other sites More sharing options...
RandomBass Posted April 8, 2016 Share Posted April 8, 2016 If I remember correctly the two ax valves are in the preamp, the au is the phase splitter. Geoff Quote Link to comment Share on other sites More sharing options...
