This is a very rare Berlant Concertone MCM-2 Tube mixer. (4) 12ax7 preamp tubes and a single 12at7 in the line section. The original schematic is under the original bottom panel. This is berlants version of the Ampex MX-10 and goes with their tape machines. After testing this unit with a plug in transformer I found the frequency response was better in the low end and high end without transformers. In the original manual it states to simply use jumpers if you do not have the transformers, I personally soldered jumpers underneath which allows this unit to shine and sound amazing on all 4 mic inputs. I did the same on the output as well. I much prefer this unit to an altec 1567 and the berlant sounds REALLY good. I changed all the electrolytic capacitors and some resistors to have this unit running strong and sturdy and safe. I left ALL the original coupling caps for tone and all the vibes you want. I cannot promise you how long these vintage caps will last in spec and they could drift after some time, but for now it sounds great. The unit has some light floor noise but it is very low in comparison to the volume of the mics. I had to replace a few of the xls on this unit but I used the same kind as original so they blend in. A few of the xls are missing the little push button releases, which I actually prefer because they tend to stick, but all work as they should for removing them easily. I added a 3 prong chord and I did nice clean work on the restoration I did. I used all vintage tubes which all work great but again I cannot promise how long they will last, so it is always smart to have spares around in case one becomes too noisy. Video: I ran through each channel 1-4, I set the volumes diff so that you get seem diff tones, breakup and textures. I ran it mostly kinda hot, cleans up nice too. Using Electrovoice 666 mic, gibson amp, Silvertone guitar. I WAS distorting my amp a bit and the mic which is right on the grill. The Berlant will get excellent clean and distorted sounds.

Vtg PA Mixer Input Tube Pre Amp / Amplifier Altec 342B Pacific Missile Range #1

This listing is for a Vtg PA Mixer Input Tube Pre Amp / Amplifier Altec 342B Pacific Missile Range #1 Unit came with the other Altec 342B we have that has an original US Navy Pacific Missile Range Property Tag This one does not have a property tag, but came from the same lot. Previous Owner’s original notes on this amplifier: ALTEC LANSING QUAD INPUT PREAMP/AMPLIFIER RATED 35WATTS. POWER ON AND WORKING OK, BUT ONE NEEDS NEW CAPS SOMEWHERE, BECAUSE I CAN HEAR A HUM. [INPUTS] HAVE RESISTIVE NETWORKS INSIDE THE CANS, THUS MUST BE ALL HIGH IMPEDANCE INPUTS. Previously used condition with some scuffs, scratches, grime. Green covering on wood cabinet is deteriorating. Wood cabinet is rickety. Powered on – all tubes glow. Unit was tested by the previous owner who states it must need a new capacitor, because there is a hum. Power cord has old replacement plug – we recommend it be inspected and possibly replace with something more permanent. The GE 44 bulb in the power on indicator is burnt out. This is an item from a huge collection of vintage ham radio, test equipment, parts and camera equipment we are currently processing. We have many manuals, Ham Radios, thousands of test equipment and associated parts and pieces. The previous owner was a Ham Radio operator who collected all of these interesting items over the years. He really focused on purchasing equipment from special surplus auctions at the Nevada Test Site, Sandia Labs, Nellis Air Force Base, Kirtland Air force Base, etc. Many of the items we have are from EG&G, Department of Energy, NASA, Air Force, Navy, Marines and Army. The previous owner kept notes on nearly everything as it seemed to be his life-long hobby to collect, test, and document everything he owned. Manufacturing technology was not the same as it is today so imperfections should be expected. Also, these items may have been in storage for 40-80 years and could be dusty, greasy or have surface rust, spider webs, etc.
