Re: [yamahacs80] Re: what failed part...you were right! 1/2 way there...

thanks so much for your advice, here guys-you were right! i dropped a new 151 into IC1, and now the envelope is opening and closing properly. the only other issue i have now is that i can now hear the range of the card better, and yet the LPF will not tune into the range of the rest of the voices.

i have 2 more good 00151 chips at my disposal. is there another 151 that possibly drives the 00156 for the LPF? if so, worth a shot? the trim pot isnt shot, as i get some play on both of the VR's that control LPF, it just wont get into a "proper range".

scott-it looks like a new 151 chip at IC1 may solve your issue. give it a whirl....
