WPA Clear Stuff Inquire

WPA Clear Stuff

Clear Stuff Contact Lube and ReNu WPA CLEAR STUFF applied without first applying BROWN STUFF can often clear up a noisy pot or switch on it’s own, so a good strategy is to try CLEAR STUFF first.  If the problem goes away….you’re done.   If the problem comes back that’s a sign that you need to do the BROWN STUFF treatment.   Note on CLEAR STUFF:  this is Miller Stephenson MS-739 which is only sold by the ½ liter and up….very expensive in those quantities.   It’s a high tech chemical yet safe, but don’t drink it.   It&rsq..

Akai M7 mod also Roberts M8 mod

Akai M7 mod  also Roberts M8 mod:This mod turns an unusable Akai or Roberts vacuum tube tape recorder electronics channel into a damn good mic pre, in the way of the best mutt ever .   While it’s not a pampered pedigree, when well modified, it’s one that you will be happy to own and probably never sell.   It’s hard to describe mic pre character with written word, but one thing is easy enough to be said of this mic pre, namely it is warm and big sounding and makes voice and instruments more audible in the mix without having to be louder or brightened.  The Dra..

Altec 1567 Mod

Altec 1567 Mod: This Mod came about at the request of some customers who noted the fantastic sonic characteristics of the Altec 1567 Mixer due to good sounding tubed mic pres, but found some significant drawbacks that prevented the  practical use of the unit in music production. The Drawbacks  :The EQ, when not needed, still added noticable hiss to the output.   This unit has a mono output, and it’s unusual to be summing 4 mics in modern music production. Most Altec 1567 owners are only using the unit for amplification of one, or at most two mics.  Yet s..

Altec 1567A Completer Mod

Altec 1567A Mic Pre Mixer Mod: The Altec 1567A…. This Mod came about from customer’s requests to have a more complete set of mic pre controls added on to the 1567A to overcome limitations to actual practical use in music and sound recording. The Drawbacks  :All 5 channels mix into to the one output, limiting usefullness in multitrack recording situations. There are no Direct Outs for each input channel. No input pad  No phase reverse No phantom power No Mute switch The Solution :A chassis extension is added underneat..

Altec 1591A Mod

Altec 1591A Mod:This Mod came about at the request of some customers who favored the fantastic sonic characteristics of the Altec 1591 Compressor, but found the excessive gain of the input stage to be a significant drawback in that it severely over-compressed normal level signals.The Drawbacks  :  To avoid over-compression the input level controls are set so low that fine control of level becomes difficult.  With the input levels set so low the output signal is just too noisy. The release times are too longThe Solution :A switch is added on the rear of the f..

Altec 436C Mod

Altec 436C Mod:This Mod came about at the request of some customers who favored the fantastic sonic characteristics of the Altec 436C Compressor, but found the excessive gain of the input stage to be a significant drawback in that it severely over-compressed normal level signals.The Drawbacks  :  To avoid over-compression the input level control must be set so low that fine control of level becomes difficult.  Because input gain is so high and compression ratio is only 2 to 4 the output level can be quite high and thus compromises downstream headroom. Release Tim..

Ampex 350 Mod

Ampex 350 Mic Pre Optimizaton Mod: This mod turns a somewhat unusable Ampex 350 electronics channel into one of the most impressive mic pres ever!  Capitalizing on a fantastic design by the brilliant Ampex engineers this mod eliminates drawbacks to practical use in the recording of music while preserving and even teasing out a bit more of the inherent impressive sound.  The result is totally usable hot neon like sound that is unmatched by  other mic pres, a close second perhaps being the Neumann V76.  This modified mic pre has all-around utility:  it is thunderously punchy, has a w..

Ampex 601 602 mod

Ampex 601 or 602 Mic Pre Optimizaton Mod: This mod turns a somewhat unusable Ampex 601 electronics channel into a damn good mic pre, in the way of a oddly well working old car that has some bonafide character.   While it’s not the Everest of Mic Pres, when well modified, it’s one that you will be happy to own and probably never sell.   It’s hard to describe mic pre character with written word, but one thing is easy enough to be said of this mic pre, namely it is warm sounding and there’s nothing thin about it.    ‘The Drawbacks  :M..

Ampex AM10 Mod

Ampex AM-10 Mic Pre Mixer Mod: The Ampex AM-10  is a fine little mixer from the early/mid transistor era.  The circuitry is very basic Class A resulting in an overall smooth, clean sound.  The microphone input transformer is interesting in that it is very small...sometimes referred to as a “thumb” transformer.  Usually a small transformer lacks low end response, as theory says it will saturate easily and thus attenuate peaks of low frequency signal.   Somehow the  thumb transformer in the AM-10 is able to pass low frequencies with minimal saturation. The saturation or loss of low freq..

Ampex MX10, MX35 Mod

Ampex MX-10, MX-35 Mic Pre Mixer ModThe Ampex MX-10 and MX-35  are fine little mixers from the late tube era.  The circuitry is straight forward Class A (as are most tube circuits) resulting in an overall smooth, clean sound.  The microphone input transformer is interesting in that it is very small...sometimes referred to as a “thumb” transformer.  Usually a small transformer lacks low end response, as theory says it will saturate easily and thus attenuate peaks of low frequency signal.   Somehow the  thumb transformer in the MX-10 / MX-35 is able to pass low freq..
