= Leach amp - Jens Rasmussen version board group buy = == 4/3/08 == Prototype boards to be ordered soon. Tweeter board looks like a no-go unless Jens gets really insprired soon. Schemati: https://www.diyaudio.com/forums/attachment.php?s=&postid=1437115&stamp=1203842288 Pricing will depend on whether the no tooling special is still going when we order. == Modified 1/30/08 to reflect the output board options Jens has proposed == == Modified 2/14/08 with size of boards == == Modified 2/28/08 with final size of boards == The options are: = Front End: = Nominally a Super Leach that can be made into a Leach Low TIM with parts omissions and jumpers. Required for both versions. === The front end board is 13 x 11 [cm] === = Output boards: = Extended Leach - just like a detached version of the last buy. Positions for 5 NPN and 5 PNP devices === The output board is 17 x 11 [cm] === Super Leach - Jens' version of the super leach output with 4 complimentary pairs of cascoded devices - 8 NPN and 8 PNP, 16 total devices. === The output board is 23,5 x 11 [cm] === Super Leach Tweeter - a single pair of cascoded complimentary devices. Suitable for low power (such as tweeter) applications, so you don't need to have another set of lower voltage rails or waste a large board for a low power application.
