EOI- Yamaha B-1 Vfet Monster (completely restored)

Recommended Posts

Item: Yamaha B-1 and UC-1 controller, both totally restored

Location: Adelaide Hills

Price: 4800

Item Condition: Excellent

Reason for selling: Need the funds elsewhere (sad face)

Payment Method: Pickup - Cash, Paypal, COD Only

Extra Info:

 

Another sale I never anticipated....

 

This is a factory 240v unit that was given a ground up restoration last year by a highly experienced vfet enthusiast. All 18 vfet devices are original and unchanged, all resistors, capacitors (including a new design power capacitor board), diodes, relays and other transistors were replaced along with cleaning every switch, pot and contact point. LEDs were installed in the VU meters as well as new thermal paste for the giant 2SK77 Vfet outputs. Critical resistors were installed raised from the supporting board to ensure adequate heat dissipation (a known trouble spot for these amps). Finally 5 new sets of binding posts were installed to replace the original bare wire terminals.

 

The B-1 was Yamahas foray into cost-no-object concept building and remains the most powerful Vfet amp commercially made. Rated at 160 watts per channel but independently tested in the 70s by Bascom King to deliver somewhere near 220. Considering this is a solid state triode amp, thats some mean feat!

 

Comes with the small face plate for "basic" operation as well, meaning only one set of output terminals are active rather than the 5 you get with the UC-1 controller in play. Inbuilt defeatable rumble filter as well which may be a handy feature. Also supplied with a very quiet computer cooling fan which was recommended to keep the driver boards running a little cooler- this baby runs quite warm.

 

At 37kg for the amp alone and another 5 for the controller freight will be a bit but can be achieved- I'll ship the controller separately in a million layers* of bubble wrap to protect the huge and lightning fast VU meters.

 

*may not actually be a million layers.....but will be way more than adequate.

 

Pictures: soon

Recently bought the Grizz’s Modwright pre. Packing was, let me say, OVER THE TOP, which you can never have enough of. Great guy and sensational to deal with.

This beast sounds like a roller lifter big block Hemi lifting the front wheels from 1st to 2nd gear.

I can attest to that 100%.

This is simply superb and more than worthy of finding a new home immediately.

      Price: $980 Item Condition: Very good Shipping Options: Pickup is available,Audition is not available, but in-person pickup can be arranged with limited personal contact,I can ship this item Suburb or Town: Adelaide State: South Australia Payment Method: Cash, Bank deposit; PayPal without fees Reason for selling: Purchased EC 4.8 preamp Further information:  Price dropped from $1100. Includes remote and will be well packaged with free insured courier for an interstate purchaser. I preferred this EC pre to a number of others (EC and more exotic) I have used with my EC 180 mono block power amplifiers. It has only one single ended (RCA) input and one balanced (XLR) input selectable by a push button on the front which keeps the electronics inside very straightforward. But if you don't want to use balanced,  you can use adaptors to get two RCA inputs.
