Lots of questions Im afraid Im hungry to learn I have done lots of vari mu projects & experiments ....Ive made many projects without a lot of basic electronics Im trying to fill in the gaps so please bare with me, thanks
Ok here some questions some may sound silly but here goes
Firstly the Altec 436 (not got one so dont no how it sounds) i read lots of people saying they are junk no use not worth building or buying......do u have one, do you like it if so why ?? if not why ??
I see theres not a lot in them does that make them bad ?? if they so bad why are they bad.. transformers, tubes ... mention Abbey road & the Beatles suddenly that are great !! Is that just mojo bollocks, personally I dont like the Beatles or the sound they had really....there i said it....tho I love the song & the vocal sound they got on Hey Jude...Wow I love that..anyway so Abbey road thought the 436 was worth tampering with then, I wont bother asking if anyone has the abbey mod.....tho id love to see it...did Emi have the money or resources to get other compressors but thought a moddified 436 was better ?? I wonder if the mods are only the obvious ones like balance pots attack release threashold that youv all done and thats it the rest maybe hype !! If as i keep reading 436 is so crap why would EMI polish a turd.....maybe the crap sounding 436es are just not working correct after all these years......I wanna DIY one just have a listen..
The chiswic thingy seem is very similar to the 436 & I read people raving about them....are they that good ?? any better than 436 ?? circuit doesnt that that much different to me....
I noticed a daul pot for theashold on that one & never seen this on any other vari mu .....Is there any advantage ??
the 6AL5 daul diode seems to be popular in vari mu Ive seen it with a wide range of resistor values on its cathodes......18K to 510K pairs ? Is this bias point ? as I say Im lacking in basic electronics, I just read some info about bias points to help me understand.
And the resistors or lack of in some vari mu circuits on the cathodes of vari gain stage tubes.....they set a bias point right ?
And designing a vari mu we would want to choose a point that sounds good through out the gain reduction range ?
Ive noticed a couple of vari mu circuits have a little amp before the diode singnal into grids & bigger out the plates I suppose the give the diode more umfff ! does it ? does it speed up the attack ?
I thought we had to use remote cut off tubes for the vari gain stage of vari mu ?? I see some units use semi remote cut off tubes ? or other....I know PRR showed us the a ECC82 could be used but not for huge gain reduction.....so wouldnt remote cut off tubes be best everytime ?
Im currently fiddling with 4 DIY vari mu limiters on my bench comparing sounds recording vocals & listening then moddifing & redesigning any suggestions would be most welcome...
thankyou for your patience & happy new year to you all
