1588c recapping

Hey RodC. Thanx for links for capacitors. Fortunately not all capacitors should be changed. The greatest problem with the cap(10uf) which is more close to transistor package - it rests against that. But I interchanged the position of them(10uf caps) and while all OK. Also I managed to find some nomi...

I have at last finished 1628 mod. My device had a problem with the power unit: at first has changed MC1468L - ADJUSTABLE POSITIVE VOLTAGE REGULATOR - wasn't +15v. To find him now is not simple - the order long waited. Also has changed capacitors, but the problem was not in them. Eventually malfuncti...

altec 1678 mod

I finish my mod of 1678 and now it's look like this: http://i122.photobucket.com/albums/o278/vovakatya/DSC06304.jpg Wire mounting is the same as describe here. I put 1k pots for gain control but that's not enough to reduce gain with high SPL source(close drums). I was trying 5k and find those more u...

Except 1678, I use 1592a as 4 channel mic pre. I took a signal directly from a lug of a potentiometer of each channel and have deduced from on the back panel on the installed terminal. From the terminal with the help of jacks I send on 4 linear inputs of Digi002. Thus is 8 mic inputs. http://i122.ph...

Hello!
Thanks for an interesting post.
I have acquired 1678 and now I begin it to mod.
About gain and volume all is clear.
By default filter HPF works only on a mix, but not a line out .
Whether it was possible to whom to re-direct that HPF on 1678 on a direct output?
Regards
Vladimir
