Baldwin BL-1 Leslie

Zoals bekend, heeft Hammond al vanaf de "klokken-tijd" vele licensies "verhuurd", zo ook  aan de orgelfirma Baldwin om in hun eigen beheer een Leslie-box te bouwen.
Technisch gezien, heeft deze Leslie de meeste overeenkomsten met model 125.








Hij is ook op de markt gebracht in een "blonde" uitvoering.


Hier de Engelse omschrijving van een aanbieder:

Description: This vintage US made tube amplified Leslie was made under license from Electromusic by Baldwin, likely in the late 50's / early 60's. Quite an accumulation of truly vintage equipment: The Leslie tone cabinet features a dual 6L6 tube amplifier, which features a tube rectifier, the cabinet includes a nice quality original vintage 12" speaker, the woooden rotror baffle, and the same standard motor used in all Leslie cabinets. This item consitis of the amplified tone cabinet, but also includes the whol ekit and everything needed, to add Lelslie capabilities to any organ (or even guitar amplifier !): There is an original 29' Leslie connection cable (6 pin), a set of two white colored "half moon" switches and the hardware to connect these parts to an organ: a hardware box to which the half moon switchedes connect, and a power adapter that will bring power to the whole kit.

Here more detail to deepen understanding: In a standard Leslie rig turning on the power of the organ will bring power to the Leslie to power the amplifier and the motor. There are the famous "half moon" control switches, of which one turns the leslie effect on (and off -labeled as: tremolo on/off) by enabeling the motor to run (relay controlled). The other half moon switch is known as the " MEE switch", which means and is labeled as: Main, Echo, Ensemble. This allows to direct the audio signal either to the organ internal sepaker only (main), to the Leslie only (Echo) or to both Leslie and Organ (Ensemble). All the needed hardware is included here to facilitate these functions almost for any organ. Hook-up is not really rocket scienece: basically the organ needs to provide switched AC power (= tunrs on / and off with the power switch of the organ) and the organ needs to provide a loudspeaker signal to the Leslie and to it's internal loudspeker. The Leslie kit will allow to switch the organ internal lodspeaker off - that is basically all there is to it. The included "half moon" switches are designed to easly mount to any organ - incerneath the keyboard facing the front of the organ with 2 screws each. For guitar amplifier usage the basics are similar: the guitar amplfier needs to provide a speaker level signal (tapped of the speaker - any guitar amp as little as 5Watts will do. To install / wire up the power/control hardware will be somewhat more involved, as the guitarist prefers to control with footswitches instead of the included half-moon switches, but I will glad to build the additional hardware (at additional cost) Add truly vintage Leslie sound and vintage Leslie hardware to whatever yoru music right might be - modern or vintage - I can help! The Leslie Tone cabinet and the amplifier are fully refurbished with a quality detail oriented overhaul job (details beliow) - performing to original specifications and ready to perform reliably for dcades.

This unit resembles similarities to the Leslie 125.

Detailed Features, Amplifier Unit: Tube amplified with tube rectifier - output power: about 40 Watt. Tubes: 1x 12AX7, 2x 6l6, 5U4 rectifier; chassis 6 pin male Leslie input, the classic gain control - to "dial in" the desired original vintage sound!; External fuse. The amplifier includes ampliifer powered relais motor control circuitry with electronic brake circuitry. Work performed to restore this unit to original specifications: Replacement of all capacitors including the filter capacitors in the power supply, all signal coupling capacitors, rework all contacts, tube sockets and contriols including the contact points of the relais. Thorough testing and replacing out of tolerance components to restore the motor braking circuitry to original specifications - All works perfectly and sounds great!

Detailed Features, Tone cabinet: 12" original speaker, belt driven wooden baffle rotor, original US made one speed motor (can be enhanced to multi-speed by adding a modern single speed to multi speed electronic conversion module). Motor control facilitated by amplifie internal relais circuitry, which includes an electronic brake circuit. Work performed to restore this unit to original specifications: Complete tear down: all mechanical parts (including the speaker) were cleaned, and metal surfces refurbished: light surface oxidisation due to age was removed form all metal parts, re-packing of the bearings and replacment of needed rubber parts. The unit runs quiet, smoothly and was restored for long term trouble free and reliable perormance.

Detailed Features, Connection / Control Kit: 1 Original Leslie cable in good condition, 29" long (sells used usually in the $60-$90 range); 1 MEE half moon switch cover white, original 5 pin mini plug (sells ususally in the $80 range); 1 Tremolo half moon switch, cover white, 2 pin mini plug (sells usually in the $60+ range); 1 Hardware connector box: jacks for the 2 plugs that are connected ot the half moon switches - the half moon switches get connected here; Leslie Speaker outptu jack (6 pin, the Leslie cable gets connected here); Male 5 pin plug "Console" (the additional adapter get connected here); 1 additional Lelsie / power adaper: contains a 117V AC power chord, a 5 pin female plug (connects to hardware box), contains also a dual 6 pin male female connector - there is a jumper plug connected to the female ens and th emale part of the 6 Pin plug is to be connected to the organ. This kit was removed form a working installation at a 1963 Wurlitzer Console organ, is tested and it should be possible to configure/modify this kit to work with almost any organ / guitar amplifier. (complete Leslie Kits sell usually in the $300-$350 without a leslie cable)
