Community Console Builds (Maihak V72)

[matriachamplification]

Hello friends,

GOTO Here for the actual build.

Wilma has informed me of several Vintage Tube Broadcast Consoles that have been offered to us to be refurbished, but we are either not interested or not able to tackle or purchase these projects at this time.

She has received several requests regarding a V72 Console and if it can be added to our "museum." She has already began purchasign parts but sadly, the cost of these consoles are outside of our comfort level to tackle without support. Being proactive she has begun putting together a plan to bring some of these consoles into our folds.

The nice thing about Consoles designed around the V72 is they are modular. Meaning there are many parts to be refurbished in various locations.

Our friend in Korea Changsik has purchased a EAB RE85 but since had to relocate putting this amazing piece of history in storage and on indefinate hold. Changsik is an amazing technician who rebuilds many vintage audio devices. We hope to one day put the EAB RE85 into our catalouge.



Bernhard has a BEAUTIFUL Desk that is in serious need of some TLC. I won't lie, I love this desk. It checks all my interests outside of one. I would want an actual Maihak desk which is harder to find then I care to mention.



We added this to the Brewery because this is a conversation that warrants some insight. Wilma is looking for people interested in adding some Telefunken tools to their studio. In a nutshell she figures that there would be several preamps and compressors that will be built and not used in these large projects. That said, these extra's would go to those helping us build these consoles.

Is there interest from the GDIY alumni in aiding to refurbish these larger priced items?

All in all this is a very early conversation that we are happy to spearhead but are making no set plans on how this would all playout. This is only a test to see if people will engage in this conversation.

Thanks!

I am new this group. Just wondering if anyone compared to hear the sonic difference using TAB V72 vs V74 with a common fader Eckmiller MR 90 stereo passive fader for line level use? I know the gain of v72 is lower than the v74.

I know the gain of v72 is lower than the v74.

I don't think so, it's the other way around. V72 has more gain than V74.

Will V72 or V74 sound better with the Eckmiller MR90 passive fader?

 

[rock soderstrom]

I don't know. What does better mean?

Hello

I have below questions re TAB V74 connector wiring

1. where should I connect pin 5a and 5b on the Tuchel connector to minimise hum?

2. what components change to extend the high frequency beyond 20khz ? Or how to adjust the feedback to extend high frequency beyond 20khz?

3. I can see +9dB and +15dB on the V74 schematic. What pins on the Tuchel connector to connect to achieve +6dB?

Thanks

1 the preamps v72/74 is always full on only with the v74 (a) you get a small part of the volume thats mean +6 db or +15 db of gain. With the v72 it’s always 34 db of gain.

2 there is no hype in the frequency range no highpassfilter only the hole freq range from 20 till 20 k hertz more or less db up from 0 db by tides pins together setting the pins on the connector

3 as read above 1 the v74(a) could be set to + 6 db or 15 db of gain.
