100 Jfets on their way :)

Its been really cold the last two days.. I was thinking whilst walking to the train this morning that I should have worn my winter coat! (Cold by Sydney standards anyway, The Northern Hemisphere people would laugh at my notion of cold)

The weather has unfortunately had a damping effect on the progress of my speakers too. First problem is that my workspace is the balcony, and it has been very windy and stormy, so I haven't risked doing any more veneering.... Second thing that worried me was that with the wet weather I might have troubles with splitting.

So Last weekend I placed an order for 100 2SK170BL's from Spencer. He sent them on Monday so hopefully will have them in about a week. The plan is to build a B1 buffer (ultimately I suspect there will be more than one), to finally do away with the abomination that passes for a preamp in my Integrated Series 200 amp.

The B1 will I think be the easy bit... I will probably build it on perfboard...
