They fit just fine. I ran them for awhile before getting the V5s. There is an adapter/extender  that can be removed giving plenty of clearance. Later V4s sold fo the H10 had one of the singles cut so as not to interfere with board components.


Ah, good to know.

Been over a week now and I haven't heard back from Burson on my defective V5-d. Also, it appears one of the single V5's is going bad as it is starting to pop and make noise. These are the improved (?) 17 volt ones.

Yes I have. Nothing from them. I pulled all two remaining V5's out today since they are popping and making other noises. Visually they look OK, but for now I'm back to AD797 IC's for the singles.

They might be busy or maybe it's holiday for them. They will reply though, have to give it time. Sucks when problems arise though...

Hi Guys,
 
With further testing, we found that our V5 opamps could become unstable when the gain setting of the Gustard H10 is set to -12 or - 6. 
 
Our V5 works perfectly at +6 or +12 gain levels. 
 
Please make sure that prior to the implementation of our V5 opamps, the below 2 steps are taken.
 
1. Install the customised heat-sink provided by us.  This is provided free of charge when you purchase our H10 upgrade pack. (Details here)
 
2. Set the gain setting according to the photo below and make sure the -6 and -12 are in the off position.
 
Thank you all for your continuing support for us and this wonderful hobby. : ) For more information on this topic please see here: http://www.bursonaudio.com/gustard-h10-v5-ss-opamp-mod/
 

 
Warm regards

The Amp shown is set to balanced but the input is unbalanced.
