(ahh, I was wondering what you were referring to (had to "allow" some of the soundcloud javascript!).)

It plays automatically when I click on the manual link..The last tune My Otis Is Not Your Otis sounds Jeff Beck inspired.

yeah, that does sound Beck-ish (wonder what the "Beck-ish" part is, frequency wise? Something very mid-rangey?). (Am/was listening to radio at the same time and some bit on Indian history is on with a bit of tabla/jungle-ish background music, and it sort of fit that snowfields track. That's what Beck needs! :lol: )

some interesting reading in the Bock Audio (mic maker) FAQ and blog such as...

In simple circuits like the ones we use, and as used in ALL vintage mics, the mic is really a power supply modulator and as such the psu is part of the audio circuit, not separate from it. Thus any changes to psu topology report themselves as changes tin the sound of the mic.

(kind of sounds like a guitar amp!)

(plus bits on subjects like capsule cleaning, tube life, etc.)

FAQ section links page:

blog (not much there but there is an interesting bit about (the high amount of) reject tubes for tube microphone use:

stumbled on a cache of (mostly old tape recorder manuals?) schematics (primarily Ampex) and such:

http://www.ilk.org/~ppk/Manuals/

May be mostly of historical interest. Just skimmed a bit and saw some tube circuitry. Found it a bit interesting how "W.W."(apparently wirewound) resistors seemed to be the low-noise "go to" resistor back then.

(This is related to the info earlier in this thread about peaking and undamped resonances with mics like the SM57/58 which (I think) are due to reactive components such as transformers and inductors in the signal path; also, related to why it's desirable to have RF filtering at the mic preamp input.)

Good explanation by "charrich56"(Charlie) on the reasons for wanting to avoid big peaks/spikes in higher frequency response:

As you can see, there is a 14 dB ultrasonic spike in the response with a 50K load. The strings will have near zero energy at this frequency but electromagnetic noise in the environment could be picked up and sent to your preamp. A single light dimmer within 20 feet could create enough energy at exactly the right frequencies to be a problem. With input impedances higher than 50K this spike could be even larger and EMI/RFI noise could overload the input stage of the mic preamp. The mic preamp may or may not be able to filter it out but you don't want to find out the hard way.

some cassette multitrack related links (speed mod, guts, disassembled motor pics) :

(I noticed cassette tape seems to be getting quite expensive. Looks more and more impractical to use cassette multi-tracks.)

Good stuff, thanks Dai.
I still have a small stash of cassette tape to keep my porta-one going so I haven't noticed current prices, things must be getting harder to find.

yeah, I hadn't checked in (probably) quite a while. I do remember (vaguely) that one online music store here carried TDK (made in Thailand SA series? IIRC), but that might've been 7-ish? years(more??) back. My overall impression of the audio quality from the mixer sections of the ones I've had is that they are poor, so from my perspective (though there is that neat smoothing effect on the audio from the tape) it doesn't seem to be particularly worth it to spend extraordinary efforts ($$$) to keep it going, however, I saw this the other day:

so, I guess it just confirms that audio can be highly subjective and maybe situational (depends on genre--good for hip hop, horrendous for classical or whatever).
