Hammond Tone Wheel Bearings (Squealing, Noisy, Seized Up)
•Symptoms: Noisy, squealing bearings or organ won't start because bearings have seized up.

•Cause: Organ has not been oiled for many years or oil is not reaching some bearings.
•Solution: By the time bearings start to squeal or seize, regular oiling procedures are inadequate. The bearings must be oiled directly.

•Affected Models: All Hammond Tone Wheel Models (Model #s starting with letters A,B,C,D,E,G,H,L,M,R,T,X)

•Procedure: Access bottom of tone wheel generator and oil each bearing directly, then apply Hammond oil generously through oiling funnels.

•Cost: Usually our minimum charge plus the cost of oil covers this repair. Occasionaly more is needed.
Choppy Vibrato on Tone Wheel Organs
•Symptoms: Choppy Sounding Vibrato on A, B, C, D, E, G, R and T series Organs

•Cause: The Vibrato Scanner is plated with zinc which has a tendancy to grow crystalline whiskers called dentrites. The dendrites short the scanner's terminals to ground.
•Solution: Replace the Scanner with a rebuilt scanner.

•Procedure: Our rebuilt Scanners have been completely disassmbled, cleaned and lubricated, removing all dendrites. We then seal the scanner chassis to retard the growth of dendrites.

•Cost: $285* - Exchange Required
Yamaha Digital Pianos - Sagging Sluggish or Sticking Keys
•Symptoms: Keys sag or are sticking or sluggish, etc.

•Cause: The Keys break or crack at the rear pivot point of the key, typically lean a little to the left, then won't move up and down freely.

•Solution: Replace keys showing symptoms described above with new reinforced keys. In situations where there is recurring key breakage, purchase of a new keyboard assembly, one having all reinforced keys, may be considered.
•Affected Models: This problem is often present on the following models although this is not a complete list of all models affected : CLP110, CLP115, CLP120, CLP130, CLP150, CLP170, CLP175, CLP220, CLP230, CLP240, CLP270, CLP280, CLP910, CLP920, CLP930, CLP950, CLP955, CLP970, CLP990, CVP103, CVP105, CVP107, CVP109, CVP201, CVP202, CVP203, CVP204, CVP205, CVP206, CVP207, CVP208, CVP209, CVP210, CVP600, CVP700, P60, P80, P120, PF500, PF1000, and many YDP models.

•Cost: On most models the cost of key replacement is covered by our minimum service call charge plus the cost of $12.00 per key, or plus the cost of a keyboard assembly (between $700 to $800 for most models).
Yamaha Digital Pianos - Excessively Noisy Keys
•Symptoms: When keys are played they are clunky and noisy
•Cause: Over time the Key felts compress and degrade allowing the hammers to noisily hit the keyboard chassis.

•Solution: Replace Key felt pads restoring sound level and operation of keys to new condition

•Affected Models: Many CLP, CVP, P, and YDP series models.

•Cost: $230*
Kawai Digital Pianos - Keys Weak, Uneven, or Too Loud
•Models Affected: CA330, CA500, CA600, CA800, MR270, MR370, MR3000

•Symptoms: Keys are uneven in volume and dynamics. Some may be weak or ring out too loudly.

•Cause: Rubber contact keyswitches are worn out.
•Solution: Original rubber contact keyswitches are no longer available; however, Kawai supplies a newer type of keyswitch assemblies to replace the old.

•Procedure: Remove old keyswitch assemblies, make a simple modification to the keyboard chassis and install newer type keyboard assemblies.

•Cost: Parts and Labor $545.00*

Roland Digital Pianos & Keyboards - Excessively Noisy Keys - Broken Sub chassis & Compressed Felts.
•Symptoms: Excessively Noisy Keys

•Cause: On models using the PA-5 keyboard assembly, as felts compress, the hammers travel too far breaking various sub-chassis and other related parts
•Solution: Replace felts and broken sub-chassis parts. Complete disassembly of keyboard is necessary. While we're in there we lubricate all pivot points too.
•Affected Models: DP-1000D, DP-900, F-100, F-100-BK, F-90, F-90-BK, FANTOM-S88, FANTOM-X8, FP-3, FP-5, HP103D-LC, HP103D-MH, HP103-MH, HP103-PE, HP107D-LC, HP107D-MH, HP107-LC, HP107-MH, HP-147R, HP-147RD, HP-147RE, HP-237LE, HP-237PE, HP-237R, HP-237RD, HP-237RE, HP-237RPE, HP-2D-MH, HP-2-MH, HP-2-PE, HP-337, HP-337D, HP-337E, HP-337R, HP-337RD, HP-557R, HP-557RD, HP-557RS, HP-7D-MH, HP-7-MH, HP-7SD-LC, HP-7SD-MH, HPI-5, HPI-5A, HPI-5AD, HPI-5D, HPI-5D-LC, HPI-5-LC, HPI-7D-LC, HPI-7D-MH, HPI-7-MH, KF-7, KF-90, KR-1077, KR-1077M, KR-1077M-I, KR-15M-PE, KR-15M-PM, KR-15-PE, KR-15-PM, KR-17M-PE, KR-277, KR-277D, KR-377, KR-377D, KR-577, KR-577D, KR-577P, KR-577PD, KR-577S, KR-5D-MH, KR-5D-MP, KR-5-MH, KR-5-PE, KR-7D-MH, KR-7IRD-MH, KR-7-MH, KR-7-PM, KR-977, KR-977-MH, MP-300, MP-500-BW, PT-2700, PT-3100, RD-700, RD-700SX

Suzuki Digital Pianos - Sagging Keys, Sluggish Keys, Sticking Keys
•Symptoms: Keys sag or are sticking or sluggish, etc.

•Cause: The weighted hammers in the keyboard action hang up on the pivot rod that runs internally through the length of the keyboard.

•Solution: Suzuki now supplies a kit that replaces the pivot rod and lubrication grease. When installed, this kit completely and permanently cures the problem.
•Affected Models: DG401, DG502, DP77, DP700, DP1000, FP-S, GP-3, GP-7, HG275e, HG425e, HG435ex, HG450ex, HG500ex, HG550ex, HP7,
HP8, HP75, HP80, HP85, HP97, HP99, HP100, HP105, HP255e, HP275e, HP300ex, HP425e, HP550ex, M22, MDG100, R21, S350, SC10, SD10, SS100, ST-7, TSI, VG17, VP1000. This is not a complete list of models with the pivot rod problem. If your model was manufactured between 2002 and 2012 and has "Made in China" on the serial number tag, then it has the pivot rod problem.
•Requirements: None

•Procedure: This modification takes about 1 ½ hours to do and can be done in your home. The modification frees up the movement of the keys and hammers, giving the keyboard a slightly faster action. The noise level of the keys is slightly increased.

•Cost: $405.00* for most models, $555* for pianos with Auto Player
Early Leslie Tone Cabinets With Fast and Off Speed (No Slow Speed)
•Comment: Even Though Not a Malfunction, This Annoying Condition Can Be Addressed.
•Symptoms: Older Leslies Provided Fast Speed Tremolo and Off (No Slow Speed)

•Cause: That's the Way They Made Them Back Then.

•Solution: Install Leslie Two Speed Motor Controller from Benton Electronics. This Device Will Run the Existing Motors in Both Fast And Slow Modes and also replaces the tremolo relay. Optionally, a Leslie Brake Function can be added.
•Procedure: Install Two Speed Motor Controller from Benton Electronics. Lubricate Motors.

•Requirements: Existing Motors Must Be In Fair to Good Enough Condition.

•Cost: Parts and Labor $785.00*
Conn Organs - Keys Sound Intermittently, Uneven or Weak
•Models Affected: Many of the 600 & 700 series models

•Symptoms: Keys are uneven in volume. Some may be weak, dead or intermittent.

•Cause: Copper wiring inside vinyl coated bussbars has oxidized causing poor electrical connection.

•Procedure: Replace all vinyl bussbars with gold plated type and clean keyswitches.

•Cost: Depends on model, current price of bussbars and location. Call for price.
