A gorgeous 1960s Brüel & Kjær type 2112 all tube stepped 1/3rd Octave band pass filter in action shortly after being returned to life at Hideaway Studio and modified for creative studio use.  The filter is simply being fed with a single sustained Solina like string pad and a series of quite haunting harmonically related pads result as the frequency control is moved between 5 different settings.  The filter has around 60dB per octave slopes. The resulting audio sounds very different to the original source material!

A single loop fed into a pair of late 1960s Brüel & Kjær type 2112 all tube band pass filters following restoration and modification for creative studio use at Hideaway Studio each manually tuned in 1/3rd octave steps to produce a shifting harmonic effect...  the content of the loop is never changed - the perceived note changes are only due to their harmonic content being shaped by the highly selective nature of the filters.

Testing out a gorgeous 1964 all tube/valve Brüel & Kjær type 1013 Beat Frequency Oscillator just after being returned to life for the first time in decades at Hideaway Studio.  The Type 1013 is a close relative to the infamous "Wobbulator" at the BBC Radiophonic Workshop put to good effect by Daphne Oram, Delia Derbyshire et al during the 1960s.

A Man Who Only Ever Left Home in the Rain

100% synthesized water effects made by feeding some randomised FM bell like sounds from an Orla DSE24 and pink noise from a Bruel & Kjaer type 1405 fed hot via a tube mixer into a gorgeous 1965 Bruel & Kjaer type 1612 Band Pass Filter Set.   Around 60 samples were captured with the filter set to each of the 3rd Octave frequency settings and then loaded across the keyboard and auditioned live in various combinations....

The classic Bruel & Kjaer Band Pass Filter Sets such as the type 1615, 1612, 2112 and 2113 are made up of banks of very high quality passive L/C resonators and are extremely selective with very high Q factors and have a sound all of their own!  There are few studio filters that could come close to achieving the same effect.

1965 Brüel & Kjaer type 1612: Waterwerks (SFX With Lab Gear)

Awakening yet another late 1960s Brüel & Kjaer type 2107 Frequency Analyser from a decades long slumber for full assessment.  These amazing all tube swept regenerative band pass filters are now very elderly and really do need very careful inspection prior to being recapped and modified for studio use. 

In this case the unit has been slowly powered up to 50% mains voltage in stages on an isolated, current limited, Variac to determine overall condition including the state of the custom main ganged tuning pot assembly which is sadly prone to contact noise in the upper quadrant.   They can sometimes be removed, cleaned and rebuilt but thankfully in this case it passed with flying colours so another unit now awaiting full restoration and hopefully an interesting future.

As you can hear in the recording, these units will run at 50% but its resulted in some rather nice tube saturation in the process :)  In this case the unit is filtering a noise source with the regen control turned in the high position.

I have overhauled so many of this era of B&K by now that I can safely say that the chances of sometimes spectacular HT cap failure in these units is just too high to be taking chances and simply plugging them in and hoping for the best.  For the tube era units, even if they fire up, it won't ultimately turn out nicely - these remarkable beasts are too precious to be treating that way!
