oh, after picking up my second holden/wasp amp this week i thought i should start a holden/wasp club. for anyone who doesnt know, holden/wasp amps were made in australia and new zealand (actually 2 separate companies, but essentially the same product). they made valve amps for guitar and bass from the mid 60's until the late 70's or possibly early 80's. this club is for anyone who owns, or did own a holden/wasp amp (guitar or bass amp). as member #1, here are some photo's of mine. These are the 2 amps (on top of a homemade 1x15). the 4x12 is a holden/wasp 4x12 which has 4 plessey 12u50's in it. the top is the recently aquired VBL (vocal bass lead) and the one underneath is the XL (designed for guitar, changing a couple caps makes it sound great for bass too if you like a bit of grit). both of these run on 4 6550's, but i believe the VBL may be running class B giving it more output (guy i bought it from said that it could put out 307W before clipping, and inside i found a sticker which may be from the manufacturer which has a date (december '78) and also says 270W. the XL should be pushing out roughly 200w. neither amps have a master volume. [edit: after a bit of research, im pretty sure they are both 200w. 270 or 300w is quite unlikely. either way its loud] heres a photo showing the chassis removed. notice the difference in the transformers. the VBL (right) has a larger power tranny by far, and probably a slightly larger output tranny (taller but narrower). when i get some spare time i will be doing some research into the preamps and power amp circuitry. heres a link to a photobucket album with some more photos http://smg.photobucket.com/albums/v643/black_labb/holden wasp/ post a photo or description of yours to be a member.
