Those later vacuum tube circuits were absolutely crazy. The workmanship required must have been insane.

They were the most under-rated organ of it's time. As a lad of 17 years old we used to sneak into pubs and often back then, there would always be a organist giving the patrons some good tunes, I loved it, my favourite pub at the time, the Sportsmans had a resident organist who played a Lowery it was bloody great. We also used to go to a dance hall in Chester, Quaintways cake shop during the day but on a Saturday night on the upper floors there was always a big band on the 1st floor and on the top floor rock bands and every Saturday night we used to go there after the pictures and watch a group I really loved to watch, Barabas Hands a Doors tribute band and the keyboard player had a Lowery with two fuck off Leslie speakers, it was a screamer, it really was. I wasn't even aware of Hammond organs back then and for me up till the present day, the Lowery organ and Leslie really is the sound to shoot for. Your Heritage clearly needs the contacts cleaning and a recap all over it, I would think more so than the neon lamps, as you will know a lamp is either working or it isn't working. Yeah! great nights those, always missed the last bus home, the last bus was always 11pm, the last song was always mid-night. At least there was always a free curry at the gig and the girls always wore original mini-skirts , who was worrying about a bus? Well done Steve, excellent video. 😎👍

Thanks Graham! Lovely to hear your recollections. Yes this organ is on my list of fixers - sometime when i have a free week I will recap it all. I moved it yesterday and the mains cable cracked off on my hand. Some quite brittle rubber in thing. I have avoided doing anything to it owing to the rats nest of wires and the amount of dust and dirt covering everything. Soon I will sort this

@@VintageKeysStudio Yeah. Soft brush and a vacuum cleaner would be the way to go. Take a 1000 photographs of everything on your phone. Valve pins tarnish something awful which will affect the circuit , be careful pulling them out, just the action off pulling them out and pushing them in a few times will be enough to clean them although a little contact cleaner will help while you have them out and don't be tempted to wipe the valves with a damp cloth as the printing will most certainly wipe off and you won't know which is which is which. Those valves are probably worth more than the organ because they're the ones which the guitarist love in their valve amps. I considered buying one of these Heritage organs a year of so back, just for the valves but it was down the south of England and would have been 8-9 hour round trip which was a shame. Good luck with it and I'll look forward to seeing the other two Lowery's when you do them. 😎👍

“Blowing this organ!” What kind of channel did I subscribe to 😂. Seriously though, I love them old lowery organs. Great video Steve.

Another interesting video. Not an organ I've come across. The background noise (called "beehiving") is common on analogue electronic organs. It's due to capacitive coupling in the cable harnesses & key contacts. Sometimes a poor earth connection in the keying area goes high(er) resistance & makes the effect worse. Nice to see & hear some of the more advanced features. Keep up the good work.

Great video. I owned a similar Lowry with a cassette recorder built into it. I gave it to a friend and it sits (unplayed) in her living room.

90v neon lamps are still common. The labor involved in repairing a Lowrey of the vacuum tube type with divider technology is a nightmare.

@@VintageKeysStudio I love it when we can see the withinnards as well as hearing what it can do. I'm not musical by any stretch of the imagination, but am always interested in the electronics.

Tone Color only works as a coupler to the Quint, so the Quint has to be engaged first. It then brings out the higher harmonic already apparent in the Quint to create an octave effect. Alan Haven's 'Image' begins with 16' Flute / Quint / Tone Color. This is an important feature as it helps the DSO sound cut through, esp. during solos. Both the Holiday TLO and Berkshire TBO lack this stop which is why they're not as good (or nowhere near the DSO price). The pedal burble is being caused by a resistor failure within the pedal chassis assembly. NE-23 neons are available and will fix your dead tones - they're not expensive. UK tech Drawbar Dave is now the primary vintage Lowrey restorer and is based not far from you. He can fix your pedals and help with neons. He owns a model Heritage DSA.

I have a full size festival in pretty decent shape. I’ve always wanted to make a sample library out of it, but don’t know where to begin. Apparently getting the negative synthesis right is very difficult. It’s very sad. These organs are starting to disappear from the earth. I always wanted to have that Garth Hudson sound.

Hi Steve, Me again. I think these bulbs lightening up while keys are stroked are similar or identical to the ones I have in my Philicorda 22 GM 751. It is the tube version. I don't know if yours is the newer one with transistors, they are identical from the outside. The bulbs are called "Gas-Filled Switching Diodes" and they are named ZA 1001 (sounds like a secret weapon in an old James Bond movie). They do not exist any more and the only way you can find a replacement is from an old donor organ. An engineer told me once I could replace them with ordinairy bulbs, but I should test different types. I think the issues you have on this organ are mostly due to leaking capacitors, bad tubes and bad key contacts. I think that under each key there should be a number of fine pins touching a cable. Some of them could be warped or dirty. It can be pretty tricky to clean or bend them. Good luck! Greetings from Paris! P.S: I'm waiting for the shaved shark song, haha

Cheers Minos - yes I have the tube GM751 too and it has the same diodes. I haven’t really done much with this organ since I got it other than replace the power capacitors for safety. I cleaned the key contacts when I first got it and it seemed to improve, but it has been sitting about for about 8 years since then and needs doing again! It is ok my long list of fixes! :)

Superb presentation. 👍👍👍

Sounds very similar to the transistor Gibson G-201 (2 manual version of the G-101 famously used by The Doors) built by Lowrey.

Mike Ratledge was using this model if I am not mistaken, many of the sounds you play are exact reproductions of those can be heard on the first 3-4 Soft Machine albums.

Thanks very much - I am not really sure about attaching a Leslie to a later model like that - I would imagine that it should just work with the correct lead out from the back of the Lowrey and into the Leslie speaker. I advise finding the Citation’s user manual - it will have all the details in there.

This video starts with a new kind of hybridized electrical woodwind organ - sort of a blowing device, a blower which gets the job done ... So you can simultaneously reed-play and ride the lightning the same time; 240 volts are quite enough for a heart-touching performance. Envelope settings: full attack ;-)! But seriously the tone chord addition shown from position 13:49 is really intriguing for me. Is this some kind of implementation of the chord scale theory? I've read some about and how to choose a scale while improvising regarding a optioned chord extension. (Oh my gosh, I hope this makes any sense in English ...) Hot to theoretically fill the scale from tonic and avoid the "avoided notes" that way. Is it that what the Lowrey do by a filter/mixing circuit or due to new assignment of the upper notes in real time? Would be kind of crazy if the analog circuitry could do the last. (Would be almost like the just intonation plugins for modern age DAWs, like Hermode "HMT" tuning.) At the moment everything which contains more than two diatonic half steps per octave is black (keyed) magic for me so unfortunately I can not rely on my ears here. Thank you - as always - for this great review. Now I have something to do in addition when thinking about the "Vox Humana" switch on the lower effects bank. Where to put the human into the casing, where the voice comes out, has that foot hole another deeper meaning ...? All the best :-)!

The Heritage DSO range has a factory-installed kit on its generator panel wired for a model 45/47. It also works with a 147 - so it's plug in and play. There's an 'external Leslie' tab on the right cheek block - once engaged it routes the organ's signal to the 147.
