New to the Board -- Kustom K100 C-6 Questions [message #7022] Sat, 10 June 2006 20:34   Jasonaf Messages: 2 Registered: June 2006 Location: Burbank, CA Junior Member Hello, All! I just received a Kustom K100 C-6 Combo Amp on long term loan from a friend, and I'm trying to figure out how to get the most out of it. By searching around on this board, I've figured out that it was built sometime in early 1970, which makes it the youngest amp in the house. Is there anywhere that I can find an Owner's Manual for this beast? What's the difference between the "Low" and "High" inputs on the front panel? What's the purpose for the other two 1/4" jacks on the front panel? There's a male three-pin XLR jack on the back, and a female RCA (maybe) input. What are those for? I'd really appreciate any help or advice anyone has to offer. I've always admired the look and sound of Kustom equipment, and I'm thrilled to have one in the house to play with. Thanks for the great Forum -- and I look forward to reading your responses. Jason Report message to a moderator

The RCA jack is a record output jack, and all K100s that I have ever seen are two channel, so you have 4 inputs on the front. The Hi and low is a tone change That the jack gives.

I see the four inputs on the front -- two "LOW" and two "HIGH." There are two more inputs on the front, flanking the Kustom logo and the lamp. What are those for? Jason Report message to a moderator

On kustom plexiglass face plates the labling is put on the rear of the face plate and hence does not ware off, so if they where factory they would be labled. I have no idea what they do with out viewing the amp in person. Report message to a moderator

I believe that the 3 extra jacks are not factory and were added. I think the XLR jack could be a DI-out. I think the extra two 1/4 inch jacks in the center of the front panel could be an effects loop. -Les S Report message to a moderator

To prove out the effect loop possiblity you would first want to plug a cord into eitheir un-marked jack while playing thru either channel, since the place to patch in a added effects loop would be from the out of one of the preamps to the driver board, if nitheir channel cuts out while trying a cord in both jacks, than they are not for a effects loop. They my be a preamp out from each preamp, in which case the first thing to do would be to get a dc volt meter, set to around a 20 volt scale, than plug a cord into each jack with the meter across the tip and sleve of the other end of the cord.If no voltage is seen then you can remove the meter and plug the cord into another amp and see if you get signal, with out playing you should hear preamp hiss just like what you hear from the kustoms speakers. If the hiss is realy loud than this is too hot of a signal to put in a preamp and should only be used to drive a power amp. Report message to a moderator
