I am still using 500 series and 1272s, just not on everything.
Gotta have a 512 on snare.

[Oldschoolwax]

Oh yes! BTW your old Pacifica is quite happy with its brothers! (enough thread hijacking!)

Here is a Jay Leno line:

The Harrison board is so good........
That is can make vocal on a Neumann 103 sound decent.

I've seen 40 input MR-4's with automation go for $500.

I've seen mint Neumann U67's go for 85€ in the early 90's (it just wasn't in € back then). And EMT 140 plates for 100€ just few years ago and bunch of Studer consoles for few hundred €'s etc etc. But it doesn't mean that this is the value!

Like I said, there's always been good deals when somebody want's to get rid of something.

That being said, if you're out for buying an analog console, it is the buyers market, big time.

That it is, also requires some luck, mine was local of all places.

That console is: the phat'ness

Wonder how long it will take my tech to recap 72 modules ?, he says it takes an hour and a half just to do one.

We did a recap session, one guy removing & cleaning and the other installing new ones, we did one channel in 20-30min. It's very hard to do it faster than that, although we tried, I think we clocked one in about 15min. Nice sport actually

I like that, get the jod done in a hurry, since I am not the best with the iron, my tech guy will do it all.

These are NOT Jensen transformers by the way! In fact, nobody now can remember who made these ones! Probably wound in somebody's garage.
It is said that the feedback output stage was developed to improve the appalling distortion figures because of the transformer. But many feel that this output stage is an integral part of that Harrison sound.

Well, at least the JE-115-K-E transformers in the mic pre's are definitely made by Jensen as they still do them...

but the JB-499-A-I output transformer is a bit of a mystery indeed.

[Ampex185]

I was talking about the O/P transformers. Your previous message implied that the console was ALL Jensens.

[jeremyglover]

Hey AllABoutTone, hope your enjoying the MR3.

i assume one transformer is for the direct out, is the other transformers for the line input or the preamp? cheers, jeremy

[wilmot]

You didn't look hard enough...there's at least two adds in the GS 2nd hand classifieds selling those VCA'a right now.

Make a search "Allison Research"...

[jeremyglover]

wilmot, would MR2 schematics help? i can email them to you.

[wilmot]

; yes they would jeremy.they would be a help i have found that mr2-mr3 and tv3 have a lot of the same circuits. e-mail to kid286@juno.com:: thanks for the help
wilmot

[jeremyglover]

ok, i'm flying back home on monday so will send them then.
jeremy

[AllAboutTone]

Hey Guys, Wilmot is a very talented/smart guy, he is my tech and one of the best I have been around, thanks for any help you are giving him on the specs etc.
What would I do without Bill ?


Telefunk, I don't think he has enough post or been a GS long enough to see the classifieds. He might have to look under my user ID.

ah, sorry about that! Didn't know new members can't see them!

I only have schematics for 32c and 24c series. I can send them if it helps. I also have the schematics for ECG101 if you need it.

Just tell me if i can be of any help.

[Melgueil]

I saw one of these (or similar) in Wizard Studios in NY, circa 1982. Al DiMeola was mixing his live Tour De Force record there at the time.

Telling myself I`d better check out of this thread - I have been thinking about picking up a few of the Great River 500 Series EQ`s ...with each successive post my GAS attack is getting worse.

Great thread - something very, very special about pieces of gear like we're seeing here. I can only imagine mixing on this thing.

Does it..., could it.... get any better ?

Basically the stock transformers on the MR2 and MR3 are the Output to Tape Feed and the Output to FX Loop Feed. There may bave been optional Mic Pre retrofits from the factory, but the stock Mic Pre didn't have a Transformer. Telefunk, Can you take a picture of one of these Mic Pres with the Jensen 115s and post it. Curious to see how this was installed on these channels.
I'm Running a 26 Channel MR2 that I Hand Built the Console Cabinet and Frames and hand wired the 4 Motherboards on. This particular set of Channels did not have the Transformers. My understanding is there was a less expensive transformer delete option on these. I'm in the process of interfacing the MR2 with a Pair of Focusrite Saffire Pro 26s and a Pro 10 to give me 24 A/D D/A. Playback is working fine.... However the signal from the Mic Pres is a little weak and I am working on impedence matching. Thinking about reinstalling some Output Transformers.... Any Ideas on this would be greatly appreciated....
Thanks...Take Care,
Shawn

I can also post some pics, but it will be at least Sunday, going out of town Saturday, be back in touch.
I have 2 MR3s

[sameal]

sorry to go off topic here, but i have a allison research egc 101 vca still on the board from a Harrison console as well as some buttons and switches and such.

i got the p&g d20059 fader, cap and mounting screws too.

I'm basically hacking the e.q. out of a channel, so anything not necessary to the e.q. section i don't need and am willing to sell or trade.

[SAnthony]

Most of these components originally came from Harrison MR2 Serial#0008, which was originally a 52 Channel Desk first comissioned at an Audio Engineering Training Facility in California. Currently it is 26 Channels. Motherboards are completely wired by hand. Elco 56 connectors on the rear and FX loop Patchbay on the upper right. Original VCA assemblies are also handwired and hopefully will find their way to a USB interface to wake up the original automation circuits.
