gavinwsmusic Posted September 23, 2011 Posted September 23, 2011 I have a 1988 H140cm. I have been trying to figure out what the pot values are. I was thinking about upgrading the cap and pots if necessary. The cap is a silver Sprague .022 uf. If anyone knows whether this is OIP let me know. I haven't really noticed the top needing much improvement but I did notice in another thread someone said they figured out their Heritage's pots were 250k, and I would much rather have 500k all around. I know they are CTS but i can't figure out what value they are. The solder is in the way, though I can see the neck tone says 70-033. The bridge tone has a different number, the solder is covering the middle but it starts with 925 and ends with 402-001A. Both volumes have PW 8824. Any help would be great, I searched online and could find anything other that serial number identification. Interestingly enough, based on the serial numbers they date to '78. Which means they sat for 10 years before Heritage put them in my guitar. I might just get new 500ks and be done with it, then at least I know.
mars_hall Posted September 23, 2011 Posted September 23, 2011 If you really want to know, open the control cavity, snip the easiest removed wires from one end-lug of the pot so nothing is connected there, then measure across the outside lugs. Otherwise you will be measuring parallel paths. Here is how CTS codes their pots http://www.ctscorp.c...asheets/450.pdf
kbp810 Posted September 23, 2011 Posted September 23, 2011 If that sprague is in a silver "metal" housing, I'd bet for sure it's a paper in oil. If you're happy with the functionality, taper, and feel of the current pots; I'd say leave it be despite what value they may or may not be... but as Mars_hall said, if you must know a quick de-solder and a multimeter should reveal the answer for you. Meanwhile.. how about some pics of that 140
gavinwsmusic Posted September 24, 2011 Author Posted September 24, 2011 Thanks for the help with the pots. I think that I will leave it as it is, for now...though I have been interested in trying out the 50s wiring to get a feel for how that works. I will get some pics posted soon of the guitar, for sure. Also, thanks for the help on the caps, I kind of figured they were PIO but wasn't positive.
H Posted September 24, 2011 Posted September 24, 2011 ..though I have been interested in trying out the 50s wiring to get a feel for how that works. Welcome to the HOC The 50s/vintage wiring is worth the 5 minutes it takes to do (unless you're fixing up a semi-hollow) IMHO.
gavinwsmusic Posted September 26, 2011 Author Posted September 26, 2011 I posted some pictures of my Heritage H-140cm. I created and album under "Heritage H140cm with bigsby" in the gallery. http://www.heritageownersclub.com/forums/gallery/album/347-h140cm-with-bigsby/ This was my first guitar. My dad bought it for me about fifteen years ago when I was in middle school. He got it used for 250 bucks at an acoustic guitar store in Portland, OR. I had it about a year before I made the mistake of leaving it on my bed when I left the room and my brother, jumped on the bed and the headstock came clean off! Man was my dad angry. I put away for about 10 years until I pulled it out and had the headstock repaired professionally. I use this guitar for everything now. I still worry about my headstock coming off but it is solid as a rock now. I put on the bigsby myself and unfortunately I used the standard Les Paul size, which I didn't realize was too big for the short h140 body length. So when I put it all together the string came off the bigsby at such a sharp angle they rest on the bridge before they got to the saddle! But then I had the idea to grind down the bridge where the strings are and provide enough space. Works fine now. You can see this in one of the images I posted. With the bigsby and a broken headstock, and the sharp break angle from the bigsby I am astonished at how well it stays in tune. Better than any guitar I have ever owned! Shows how well Heritage guitars are made. The neck is a '57 classic and the bridge is a Humbucker sized p90 by Lollar. I never liked the Schaller's it came with.
kbp810 Posted September 26, 2011 Posted September 26, 2011 Very nice! The classic 1980's cherry burst finish That headstock repair should hold just fine, it should actually be stronger than ever with a proper repair.
