Vintage Tube Amp

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.

This is a very early golden age RCA Monitor amp from the famed Sun Records 76 Console. This monitor amp is also PERFECT for the audio lovers out there who use RCA turntables and wanna listen to music on this incredible amplifier! Has huge UTC input and output transformers. The transformers all test perfectly. The input transformer reads 5k on the ohm meter which is actually 50k ohms the normal mic/line ohms for the secondary of the input transformer. Also reads perfect for the 150 ohm and 300 ohm inputs on the primary. The output transformer reads perfect too as shown. The amp has not been tested further or turned on. It needs FULL restoration before it is turned on. What you see is what you get. It has wear and tear throughout but should restore easily with a tech. This is the holy grail for audio listeners or recording folks. This monitor amp can also be used as a mic preamp or line amp. (4) 6j7′s and a pair of 1621 power tubes which are 6v6/6L6. If you have an offer send it.
