dropped the price to $200

Pair of excellent HD650's for sale. I have had these for a number of years and very little use. Less than 20 hours probably. Will come with original box and packaging. Not sure of the date of manufacture but probably around 7 years ago.

I am thinking about adding a set of inputs and a toggle switch to my Crack. What is the best way to drill holes in the plate? I have a stepped drill bit and also a dremel. Do I need a punch, then drill? I don't want to screw up my plate.

This stuff: Frost King Moretite   Also sound deadener sheets.

Wanted to post my completed Crack and setup. Listening to Alison Krauss "Forget about It" SACD with Yamaha YH-2's at the moment. Plenty of volume and sounds good! Got a pair of HD650's on the way too! Got that Raytheon power tube to try, plus a couple others in the bag.

Thanks everyone, It is looking pretty good. I think I will wet sand with a little tung oil to really even it out. Some of it is the end grain.  Got the paint on the cover, came out pretty well. I am going to let the top cure over the weekend, start assembly Monday!

Crack building first steps. How can I get the tung oil to soak in on the top corners? I think a little glue overlapped. I sanded lightly to remove, but no luck. Could I wet sand or use mineral spirits to open the grain?

Doc,   Thanks for the reply. That is what I was thinking, use the switch from the quickie. I emailed queen for the specifics. I wanted to use the same materials, knobs, rca to match the Crack. Just aesthetics.  

I thought about building a switch box, but the cost gets a little high with the rca's and the extra cables.   Looks like there is enough room to add a pair of rca's and the switch knob. What do you think?   Hopefully bottlehead will get back to me. I was hoping to use the parts they use...

Have any of you added an input to the Crack? I need two inputs, rather not have to unplug the rca cables. Can anyone recommend a switch, or do you know what kind of switch Bottlehead uses for their other amps? Also the rca inputs they use? I sent an email, but I think they are out of the office...

Saw this thread:   http://forums.m-audio.com/showthread.php?13279-Revolution-5.1-series-%28xp-64-Vista-64-amp-W7-64%29   Maybe you have tried this, but take a look/

Heathkit will send you a copy of the original manual for around $25. I got one for a preamp.

How would the Crack do with Yamaha HP1 Ortho's? Just discovered these cans, thinking about trying to grab a pair but don't know a lot about what type of amp is needed. I posted in the Ortho thread also.   Technical specifications: Impedance: 150 ohms Frequency Response: 20-20,000Hz...

Would the Bottlehead Crack drive a pair of Yamaha HP1's sufficiently?   Specs: The approximate specs are input impedance 100K ohms, output impedance 120 ohms, gain about 15dB into a 300 ohm load.

Thanks a bunch. I bought a pair of these. Gonna try them as coupling caps in a sacd player. We'll see how they do. I have no idea what they were designed for, thes are 1uf 300v.
