JLH update: parts on order

I've decided to order up a batch of parts for my updated, higher-powered JLH amplifier. I'm getting a slew of 2SA970s and a handful each of 2SA1358 and 2SC3421 from MCM Electronics. The power transistors (MJ15003 and MJ15004) are from On Semi via Digi-Key. Also from Digi-Key are a quartet of 68,000uF/25V Panasonic AA-series capacitors.

I also contacted Conrad of Victoria, Australia about heatsinks. The units themselves seem to be priced mighty nice (~$71 for 2), but we'll see what the shipping quote is... and if they'll get too hot dissipating a whopping 133W each!
