The Glorious Fool LP.... wonderful, and also his sublime cover of Glory Box
Fripp is destined to be remembered only for the number of youtube videos he's had taken down. He'll have single-handedly stopped anyone new discovering King Crimson. As slowly turns the grinding wheel in.... but those must have been Sinfield's words. David

Re: Vortexion WVB smoking component..
Saw John Martyn at the St Ives Guildhall many moons ago, got Inside Out somewhere from the 1970's.

The WVB and stereo CBL version are very versatile machines good enough for the BBC to use.......Meek had some interesting techniques Lyrec stereo TR15, full track EMI BTR2 as well as EMI TR51, later Ampex PR10 stereo. He did a lot of backing tracks on various machines played back the stereo tape on the full track mono machine mixed in with replay from WVB and then back down to one of the tracks on the Lyrec .....he could only bounce down so many times before he lost quality which is why some of his recordings are no so clear.....all done on the fly but it tied most of his output into mono .....same as Spector....apart from radio was mono so they were balanced for mono sound......I digress...... |

Re: Vortexion WVB smoking component..
I’m a bit late to this thread but the lack of a WVB Series 5 or 6 Manual or circuit diagram available online has caused me difficulties too when servicing a WVB. However the circuits are basically half of a CBL5 or 6, which are available. The differences between the 5 and earlier Series 4 models are mainly in the bias and erase oscillator and the 6 has a different circuit around the ‘Monitor’ output, to earlier models.
They are super machines, in my opinion, I love them. The CBL6 in my collection is my favourite. Bill |

With respect to the audio / record circuit . My father built an amplifier based on the Vortexion set-up which is completely independent of a tape recorder ( he hooked it to a BSR TD10), I dont know if this was before he worked at Vortexion (he was at Venner Time Switches before spending a short while at Vortexion). It uses similar principles of mulitple Inputs - for shielded Ribbon Mike, Gram and other mike or tape playback or line in, and has an adjustable bias (for tape, not tubes), circuit erase, and a monitor function - which basically seems to be an audio output before final amplification while the record signal goes out on another modified output line, but its not , so far as I can see, a monitoring of the signal laid down on the tape (not least because the TD10 does not have a third head , and I dont think the input signal takes a different path to the monitor compared to the record signal - I suppose I could modify the amp to the WV (Wearite Vortexion) full circuitry). The amp was badged 'Mayfair' and was either an internal reference design to Vortexion or something from the likes of Practical Wireless or similar. |

Re: Vortexion WVB smoking component..
OK, going back to the original smoking component problem: I have now replaced all dead caps and 1 blown resistor with suitable replacements and there is just the 500 Ohm 5W power resistor (the original smoking component) to replace. I dont have 500 Ohm 5W (its R33 in the series 6 schematic) but I do have a 10 ohm 5W power resistor. Am I OK to replace with this one??
Thanks again 9!. |

Re: Vortexion WVB smoking component..
Hi - is this of use? It seems to have a monitor circuit. I do have the rest of the manual, but not scanned in.

Yes, as the WVB has 3 heads it can be used to monitor and it can also be used to create echo and delay!! You say you have the rest of the manual!!! Oh my!!!!! Could you possibly possibly scan the rest of it?? If you did you would be a legend!! |

It's starting to look good. The next thing I need to look at is how to reglue the glass to the meter. It's come loose. |

Don't be tempted to use Superglue - you will end up with a white residue on the glass.

Re: Vortexion WVB smoking component..
Looking at your pics your WVB is later than my 4 (the erase switch is toggle) so I wonder if a 5 or 6? The CBL 5 might be near.

Re: Vortexion WVB smoking component..
Yes. Like I've been saying I have a series 6 WVB. I have these schematics. Thanks.

My apologies - I thought i'd read the whole thread. Skipped a page!

Re: Vortexion WVB smoking component..
You could be right about the WVB "manual" being just an addendum of the WVA manual. Lets hope not though!! (I'm guessing we'll be hoping a ****** long time.....)

Re: Vortexion WVB smoking component..
It would seem odd that given the added features and consequent complexity of operation of a 3 head m/c that nothing would have been printed. At least it would be useful to explain the ability to bias instantly and set levels for particular tape, sos, bouncing, and best practice for all those kinds of things.
I have the CBL5 book somewhere so will see if that mentions those things. If not I shall set off to Wimbledon immediately and remark on it to the Company.

I dont suppose you could find out about using it for "echo work". I understand the WVB was used quite a lot for this. I have worked out from the schematic and by plugging in headphones that the "Output" socket is used for monitoring what is on the tape whilst recording using the "monitor" control for volume but I have no clue how I would use the controls for echo/delay. I'm guessing the "before " and "after" switch comes into play but I'm not too sure. |

Re: Vortexion WVB smoking component..
Essentially, you get tape echo by feedimg some of the output from the playback head ("after") into one of the inputs whilst driving the other with your microphone or instrument. Feed in too much and the thing will saturate, feed in too little and you won't get the effect. Whether this is arranged by a particualar switch or a patch cord on this machine I can't recall - I suspect the latter.
