![]() If doing the media blasting use glass beads on low pressure as sand woud be too harsh IMEO. However, the wiring, electrolytic caps, and many other critical parts are all new, fresh stock.I need to CAUTION you all on EITHER method of returning the matted finish to the capstan (and for that matter NOT all capstans had a matted grey finish). All the good parts with mojo were tested, refurbished and rearranged. The amp's insides were completely disassembled, assessed, redesigned and replaced where needed from the ground up. It also stays huge with tons of headroom when used on more sane settings! It can be very non-linear and when cranked with a tremendous soundstage that compresses ever so lightly, much like hitting tape. It has no negative feedback in the circuit and this makes it behave in different ways depending simply on where you have the volume knob set. The design is original and unlike anything else you have used before. If you need phantom there are plenty of external power supplies available from many places. There is NO phantom power on-board by design to keep it simple. It has everything it needs and nothing it doesn't. I have strived to make this design as simple and as pure of tone as possible. For controls it has a single gain knob! Between the single gain knob and pad switch, it is all the gain control you will need. The output per channel is a transformerless and impedance balanced type on 1/4" TRS jack that is compatible with 1/4" TS and TRS cables. It also has a 1/4" DI input and a 1/4" line level input. It uses an EF86 and 12AU7 and has an XLR input with pad/phase switches. The circuits are high gain microphone preamplifier / DIs suitable for use with even low output ribbon mics. That's right, TWO channels all with their own inputs and outputs in the single monoblock. The modified 2x Pre chassis, when completed, consists of two discrete all-tube, high voltage audio preamplifier circuits inside. These modules were MADE TO ORDER by hand. Find out more details at my DIY project blog, XFMR DIY Projects Much like a modern Street Rod car, this is effectively a brand new device made using vintage parts. Each module is taken apart completely, parts are refurbished and a whole new circuit with all new wiring and capacitors are built in the donor chassis from the ground up! This is NOT a simple, mod, tweak or recap like you'll find from other sellers. Please note, this 2 channel preamplifier is made using the amplifier electronics from Akai/Roberts Tube Reel to Reel decks. ![]() ![]() Tablebeast modified Akai / Roberts TB-2XP1 module. Single Monoblock converted into a 2 channel Microphone Preamplifier - Rack Mount or Tabletop They're in perfect working order, and ready to go.Īkai / Roberts Tube Monoblock Modified Amp This pair comes in a beautifully handcrafted case that resembles a guitar amp head. Additionally, input pads and phase reverse switches are included on XLR Mic. In, Line In, and Instrument inputs provided. These are great DI's for bass, guitars, and keyboards!! Mic. They can be adjusted to be warm and clean, or completely overdriven (as Mic. These Tablebeast rebuilds of the the venerable Akai/Roberts tape deck preamps are superb examples of how vintage, all-tube mic./line amps can be utilized to provide warmth and character to recordings (for another 40 or 50 years of service). Up for sale is a great pair of custom rebuilt vintage tube mic./line preamps (original 1960's era).
