Really? I wasn't expecting that from this ampThe amp sounds fabulous.
The fan noise is a little louder
Apparently my update did not include a fan or, more to my surprise, a new powerblock or MOSFETs.The power unit update applied to my Titan did not contain a 2nd fan.
!?
side: I guess I'll keep my fingers crossed on the MOSFETs. I was really under the impression that degradation of the MOSFET terminals was a major source of problems with this amp, and one of the primary reason for the update. Perhaps they inspected the MOSFETs in my amps and it had the good ones all along Maybe the upgrade differs between 110V and 230V power units.
Replacement of the MOSFETS is not a necessary part of the update (there may be exceptions for catastrophic damage to the earliest single die devices which we discontinued years ago).
Good to know. As I inferred in the previous post, each update seems to be basically a custom job. I was surprised the amp didn't need MOSFETs and a new heatsink as I thought that was a common part of the update. But the good news is it probably saved me quite a bit of money and there is no point in replacing good parts. The other surprise is I really didn't expect the amp to sound better after the update, since it was already pretty awesome.
Glad you're on the Mesa team, and hopefully it means the Subway and future amps you design for them will be rock solid, instead of needing a spa day with the factory repair guys.
These are very complicated amps to repair, our experience is that non-authorised service techs that do not have experience with our products struggle mightily. We do not have the resources to work with techs to re-invent the wheel nor do most customers have the money to cover the cost of a tech's education on such a product. You will need to find an authorized service center in the EU (your region) and they can work directly with our service support staff to get it repaired. They will also have the ability to order the necessary parts for the repair, in some cases these parts may include rebuilt assemblies. We do not release schematics for these amps for this reason.Anyone with schematich for the Titan? Got one from a musicshop who couldnt fix it so a friend would like to have a go. Authorized Mesa repairmen dont crow on trees in Sweden.
