Velodyne's customer service is non-existent!

If you're still interested in rescuing your sub and don't mind
dealing with a repair facility across the country. I highly
recommend EBC Electronics.

The owner Paul is great to work with, he's expert in repairing
Velodyne plate amplifiers and he doesn't gouge.

I couldn't be more pleased with his work on my 20-year-old
HGS-12. Paul brought it back to life and it didn't break the bank!

I was quoted $1000 from Velodyne just for the power supply alone + service fees and freighting and I don't think that's fair. I have four DD units in my theatre..
Can you please assist?
Matt.
a complete (new) amp should cost you around $1000!

Are you sure it's the power supply failing? Those DD's are complicated built with a lot of components, try swapping the amp from another dd see if the problem remains....
No, not the amp module, definitely just the power supply. Of course I am talking Australian dollars. They prefaced it by saying "are you sitting down?" before telling me.

Is it possible to get a copy of the power supply circuit diagram so I can have one built by an electrician please?

Thanks; I went with a Velodyne repair center posted on their website, very near to their facility, and assumed they would know what they were doing.

I'm almost $700 in at the moment with a dead sub and don't want to throw good money after bad.

They will be sending a prepaid shipping label for them to take another look at it under warranty.

They asked if it was the driver but the driver worked perfectly during the rather strenuous self EQ that runs at 30 out of 100 in volume/gain and is 25 tonal sweeps that literally shake everything in the room.

My standard volume setting is 10 out of 100 with -9.5db on the AVR trim so the driver is fine IMHO.

Another member on here mentioned that DD15 parts, even in the US, are getting harder to find which is just plain ridiculous IMHO.

The DD amp is sensitive for input gain. you should lower the avr sub output so your playing comfortable volumes at 20-30/100 on the DD.

The support for DD is probably dying...

I'm at -9.5, and it only goes down to -12.0db and has been fine for 8 years or so.

At 30 gain in my mid sized room the sub would dominate the other speakers.

Using an SPL meter the sub is about 3db louder than the others already using pink noise.

Room is apporximately 18x12 with 8 foot ceilings and an opening into the kitchen area at the back right of the listening area, so, in reality, not a "small" room.

Velodyne CHT-10 Preamp section help

Dear Sirs, This is my first post in this site. I am from Argentina and I have a CHT-10 sub (220volts), and it started to make a strange sound. When disassembled, the power supply board provides the required voltages, but when I reconnect the preamp (green board, picture attached below), positive 15v voltage shorts and don't provide the required voltage. Could you please enlight me as to how to repair it? I don´t have official service in my country. Thank you in advance, SCA.
