Greetings all, So this is probably a question I should ask Nik, but I think I'd like to ask one of you good folk who have actually ordered and assembled a Ceriatone kit. I am considering a TW Express kit. When I read the descriptions of the express kits ..( well, "Expression" kits), here: http://ww...

Thanks to everyone who provided help and suggestions in this thread to help me get my clone up and running again. At this time I don't really know what caused the problem but it seems to have resolved somehow. I re-soldered some of the connections that looked suspect, including the grounding bus to ...

I will fire it up today and see what I can accomplish. I have checked the wiring on the bright switch and it is fine. I have one of the cap leads to the bright switched heat shrinked as well, hard to see from those angles. You said you also replaced one of the Bright Caps? The only cap I replaced wa...

With the amp off and the connection from the treble pot to the volume pot in place, turn volume pot and all tone pots up full and measure resistance from the volume pot wiper to ground. It should be about 670K. With the volume , and three tone settings up on full I am reading 670K on my DMM If you ...

Sorry if I wasn't very clear with my previous post. This is with the amplifier turned off actually. If I disconnect the wire from the volume pot to the treble pot, then I am reading just over 1M on the DMM with the volume on 0. I was just trying to trouble shoot the pot by isolating it from the rest...

I'll get some pictures later on today. Thanks for all the suggestions. I checked the ground with a MM and it seems O.K. Not sure about the behavior of how the volume works in a wreck circuit but the volume pot measures little or no resistance ( it's fully open at 7 o clock and on full ) when I go th...

Hi there. Some time ago I built an express clone ( Ceriatone ) and have had it working very well for the last couple of years however I had some problems with an unstable input jack so I decided that it might be a good idea to change out all of them with the vintage Switchcraft type. After putting i...
