thanks |
Hi Loss,
Go to DJB's EXCELLENT synth site (Dave J Brown) and look at his build notes for the Thomas Henry Mankato VCF. He used a couple Panasonic SMD tempco's that were purchased from Mouser AIRC for VERY little money. These are big (as tiny SMD's go!) and not too hard to solder a wire to each end. A great tempco solution, IMO. FWIW, the Mankato uses 2K , so dave put two in series, which was still less expensive than the least of the competitive choices. You'd need just one.
FWIW, the DJB link is also in the Mankato builds thread in the Thomas Henry portion of this site. (The Panasonic 1K tempco part number has been mentioned elsewhere on e-m, but this is the one I remember.)
And finally, Magic Smoke has been selling the micro-ohm tempco's at really good pricing. I don't remember if they have 1K though.
Kind regards, Randal |

Yo,
I also stock the 1k @ www.bridechamber.com , but to use the 2K you have, doubling the value of the summing resistors should work fine (to 200k and 2m), or maybe doubling the 56k... maybe ask Ken about that one. The reverse works for using a 1k w/ MFOS and MagSmoke stuff -- halve the values of the summing resistors there.
Cheers and happy building,
Scott Last edited by bridechamber on Sun Nov 25, 2007 12:16 pm; edited 1 time in total |

Scott - nice site and stuff. You might want to strip the comma off the end of your URL - phpbb3 can't parse it properly.
BTW glad you're stocking the Vactrols... |

I fixed the comma, thanks!
I didn't realize this forum was from months ago. Whoops!
Well, hopefully you got your 2K to work...
Cheers,

I think it was from yesterday so still relevant!
I always get confused by looking at the join date which was July for our poster. |
