Ha hum, I've finally succumbed and ordered an A-100 modular from Thomann (G9 Suitcase and a good variety of VCOs & modulation) but the A-126 Voltage Controlled Frequency Shifter is no longer available. Does anyone have one they'd like to sell me? I'm in London UK and could pay via PayPal. Thanks, Matt

Hi Matt, Have you tried EMIS in the UK, they may have one. http://www.aues21.dsl.pipex.com/ 0117 956 1855 Cheers Andy On 29 Dec 2010, at 15:43, Matt wrote: > Ha hum, I've finally succumbed and ordered an A-100 modular from > Thomann (G9 Suitcase and a good variety of VCOs & modulation) but the > A-126 Voltage Controlled Frequency Shifter is no longer available. > Does anyone have one they'd like to sell me?

Thanks Andy but it's listed as discontinued on the EMIS site. Matt

Hi Matt, How about an alternative, the MOTM E650 Deflector Shield looks nice! http://postmodular.co.uk/motm/e560-deflector-shield-coming-soon I want one anyway :) Andy On 29 Dec 2010, at 16:09, Matt wrote: > Thanks Andy but it's listed as discontinued on the EMIS site.

Hi Andy, Nice but the A-126 was EUR 180 so the MOTM is about twice as expensive. Cwejman also do a nice one for even more money. Matt

Hi I just sold my A-126 frequency shifter to a list member only to discover that it doesn't work anymore! The audio in and out work as normal but there is no signal at the shifted outputs. It was fine a few weeks ago and I am pretty sure nothing like reversed power could have happened - but what else could cause this? Seems like the internal VCO is probably kaput? any ideas? Richard

Hi Richard, > It was fine a few weeks ago and I am pretty sure nothing like reversed > power could have happened - but what else could cause this? Seems like > the internal VCO is probably kaput? The VCO output is jumpered to the MC1496 chips, so check that these are properly in place/making contact by sliding them off and on a few times - ST3 & ST4. Also, some of the chips may be socketted, including the PA382/CEM3382 chip which is the VCO - gently push them home to make sure that they have not worked loose. Most of the trimmers on the board are for the phase-shifting filters; those that aren't are unlikely to stop the oscillator working even if they had been touched/moved. The power supply requirements for the circuit are quite quirky too: two on board regulators provide +/-9V for some reason, and there is also a 'delayed 12V' rail (it comes up after than the main +12V rail I think), and which I think might be to ensure that the VCO does start-up when power is applied - this may be another reason for it not running, but I doubt there is anything simple to be done about it (if indeed that is the problem!). If it isn't anything simple, it will probably take a scope to sort it... Tim

got the same problem here, havent checked the MC1496s yet. exchanging the 3382 didnt make any difference

Daniel, Richard > got the same problem here, havent checked the MC1496s yet. exchanging > the 3382 didnt make any difference Discovered I have a Google translate of the service manual, and notice that there were a number of odd problems with early issues of this module - certainly mine has a diode and two caps soldered onto the underside, which I think was its final configuration, so it might be interesting to know if yours have these mods too: a biggish cap, 10uF or 33uF or so, and a smaller one, 1nF or so - if one or other is missing, then it's possible I guess that the module may have spontaneously started exhibiting the problems they fix, but a slim chance I guess! Also the IC next to the PA382/CEM3382 is better being a TL084 rather than a TL064. Most of these things were to do with stability issues, and I have little feel for whether they could potentially stop it oscillating - again, it is really going to take hooking the unit up to a scope and poking around.

jupp, got those components on the backside too
