    Thank you, sir! I really love the sound of this unit, too. :D

    Paypal is OK. The VC3 is on its way back to you now.

    For others checking this forum for information on the VC3, the fault on this one was caused originally by a failure of one or both of the input capacitors. We used a good quality capacitor in the first place, but after nearly 15 years they started to get slightly ‘leaky’ and allowed an excessive voltage to appear on the SSM2017 input chip. This caused the chip to fail. :(

    If there is excessive noise on the mic input, or a failure of the mic input, it is worthwhile changing both of the input capacitors and the SSM2017. :)

    The VC3 is back safe and sound in its rack in my studio, all fixed up and sounding beautiful again. Many thanks to you again for getting this up and running! You are a true gentleman.

    Thanks, Ted.

    The other night I was comparing the JM47 to an ADK Vienna and a TNC tube mic, and the JM47 gives so much more detail than the other two. I really like this mic for my voice.

    Sorry for the question, got it figured out. It was the high pass filter engaged interacting with what seemed like compression and high input levels. Turned off the HP filter, dialed the compression a little harder, and backed off the input level a little. Attached is a photo of my JM47 (not sure if that was your design?) with my Fletcher-designed preamp section in the rack just to share with you that your products are still being used, cherished, and appreciated! :D

    Thank you, Ted. It is on its way to you, sent out yesterday from Hollywood, Florida.

    I had my amp tech install the two new 100 uF 63v Sprague caps. I put it all back together and…….still no signal from the xlr jack. 😥

    I probably should send it to you at this point if you don’t mind working on it. I think I can send it via USPS international flat rate shipping for a reasonable cost.

    Send it to the address below, correct?

    To the left of it there are two large capacitors, they are 100 microfarad and with a working voltage of 63V. .

    The ones I am planning to order are by Mallory and are 10mm diameter by 13 mm height (100uF and 63v of course). Will that size (ht. and diameter) work on the VC3 pcb? The guy that is going to do the work told me the exact physical dimensions of the replacement caps are important to get correct.

    I’m going to try to find these online and have my amp tech unsolder the old ones and solder in the new ones. He did this for a TASCAM cd burner I have (once I told him which cap needed replacement) and now it works perfectly. Thank you, sir, for all of your responses and help!

    One more question if I may…as I mentioned previously, I also own a VC1Qcs and MQ3, and love them. In some older posts (shortly after he bought the name rights) Alan Hyatt kind of slammed the ‘cs’ version of the VC1Q on some online forums about the omission of the transformer in the preamp section and implied that the ‘cs’ version has a poorer quality preamp than it’s predecessors. Of course the change in the ‘cs’ was for a reason, be it cost or sound or both, but would you say there is a big difference in the quality of preamp in the VC1Qcs versus the VC1Q? I love the sound of my ‘cs’ (and that’s what counts), but Alan’s comments seem to have been carried on by readers and posters in other forums as a bit of an urban myth, even making it as far as descriptions on ebay, and I’m just wondering what your take on the different preamp changes in the VC1Q versus the ‘cs’ version are.

    I get absolutely nothing from the XLR now(and nothing on the input meter), and there was no crackling or humming that I remember before it went silent. Here are some photos of the inside if it helps, or I could take closeups of the caps if you tell me which ones could be the culprit.

    I did notice when I first opened up the case that the case ground wire wasn’t attached to the pin, but would that cause the xlr input not to work?

    Well, I priced out what I believe it would cost to ship it to you and pay the repair cost and came up with about 50 pounds. The only tech I’ve used here where I am (besides my amp tech) charges 50 pounds just to look at something, then additional for parts and repair. 😥 If I could diagnose the problem and tell my amp tech what needs to be replaced, I’m sure he could do the soldering work.

    So, how would one go about determining what the actual problem is (the xlr input not working)? It seems like it could be anything from a simple loose wiring connection to a faulty mic preamp chip to something in the input jack not registering that there is no cord plugged into it (just speculation…I know absolutely nothing about complex electronics). Any ideas or tests I could do to help determine what the problem could be?

    Thank you, Ted. I may take you up on that offer if you don’t mind, as I trust you more than anyone to get it going again. I’m going to take the cover off and check around with my unskilled eyes for anything obvious. If I can’t find anything, I will send it to you from Hollywood, FL, USA, zip 33020. Thank you again for your time in responding!

    Firstly, thank you for the response, as I know you are a busy man.

    I tried some DeOxit in the 1/4″ input jack, pushed a plug in and out of it several times, but still no XLR reading. :( When I opened up the box after I first noticed that it wasn’t working, the green grounding wire attaching one of the 3 pins to the metal case was not connected, so I had my guitar tech solder it back to the pin. That didn’t solved it either so I’m wondering what it may be that’s causing this. Is there anything else you could think of? I can post photos of the insides if that would help.
