JON-Did you restore the Cit I in any fashion? It's probably an interesting comparison to make! I am glad you are still enjoying the Peach. BTW, if you are ever interested we can upgrade some aspects of your Peach such as 6H30 in the V1 hole in place of the 6922. Nice pickup in transparency unless you are using a CCa or really special 7308, etc.
We have redesigned the Peach from the ground up, and it is back in production. The new Peach II with Remote is better sounding than ever, and is now available in black, silver, with or without walnut cabinet! And, it's at an even lower price than before!The Peach II basics:• 4 AUX inputs (no phono)• 3 Modes of Output - - Hi Z, Lo Z, HT Bypass (Unity Gain)• Massive Tube Rectified Supply• 6H30 zero feedback gain stage• All AuriCap coupling caps• Remote Control volume and muteGet all the details at the web site: http://www.juicymusicaudio.comThank you.
Hi Ray--My pleasure. No, HiZ mode is intended for amplifiers with a >47k ohms input impedance. The LoZ mode however, has a source impedance of about 90 ohms and will drive your 3.8k load, although that is mighty low for an amplifier. Lower than any amplifier I have encountered in 40 years of doing this. I'm wondering if you meant "38k" as the load, in which case the Hiz will work fine. You're more than welcome to call anytime with additional questions or clarifications. It's what I do. Mark

I've been looking around the net at different tube preamps. There was a lot of talk on one of the forums about the 6H30. The newer ones are tending to have a slight glare. to the older counterparts. Just was wondering what your thoughts were. Now, I'm not saying that is true, ... only telling you what I have read on the audiogon preamp tube forum. Are you doing anything with a constant Current Source circuit with the Cathode, or is that resistive. Are you using a plate choke or is that too just a resistor? There isn't really that much in an overly simple way to put together a tube circuit. My understanding is its the values that make the circuit. Between the 6922 and the 6h30, is that just direct coupled or some cap there in between the two stages? Also, is it possible to buy the Peach without the remote control. I want to use a stepped atenuator as opposed to all those pots you have there. The one I'm looking at is a 100K Ohm atenuator. So that's all at the moment. Ray
hi mark,your website says that the peach's hiz mode is the same as the blueberry's, yet the output impedance is stated as 3.5kohms as opposed to 1.2kohms of the blueberry. so, something is different, no? will the peach's hiz mode drive a 47kohm input thru long cables, say 6m?thanks,doug s.
hi mark,mebbe you missed my question the first time around? regards,doug s.Quote from: doug s. on 24 Jan 2008, 02:42 amhi mark,your website says that the peach's hiz mode is the same as the blueberry's, yet the output impedance is stated as 3.5kohms as opposed to 1.2kohms of the blueberry. so, something is different, no? will the peach's hiz mode drive a 47kohm input thru long cables, say 6m?thanks,doug s.
