There are 2 or 3 threads where this topic has been discussed, so it seems as a good idea to regroup all this in one thread. It will be easier to follow the infos. Here's an update :
- New owners of the TA-30 (mainly heads I think, would like to know from combo owners) have reported a problem with the reverb circuit. There is a noise, hum/hiss, when the circuit is on and the noise increases when using the reverb control. Not a real problem when gigging at high volume but annoying when not playing loud or mainly, when the amp is miked.
- A change of tubes in V5 and/or V6 as been suggested. I did the changes but nothing changed.
- Here is Mesa's response which seems to implie that it's "normal". I've copied it from another thread in this forum :
"This is actually somewhat normal for the TA-30's. The higher the reverb
is turned up, the more hum you will hear. The heads will have a tad
more hum due to the proximity of the reverb tank right next to the
transformers in the amp. This is usually the same scenario for any of
our amps that have reverb. No matter what, once you turn the reverb
control up, you will normally hear more hum. Some amps are just more
noticeable than others.
For most guys that use moderate reverb settings in a live gigging
situation, it's usually never an issue. However, customers that use the
amp at lower volumes in there studio/bedroom and have the reverb cranked
all the way up will be the ones that hear this the most.
There is obviously always a chance that it's the reverb tube causing
more noise than it should in V5 or V6, or that something happened to the
reverb tank in transit.
If the customer has further concerns you can definitely have him contact
us directly in customer service. Then we can further diagnose the
symptom with him over the phone while he has the amp in front of him."
So that's about where we are on this. I sent this message to the technician at the store where I bought the amp and waiting to see if he can do something. I hope that everybody concerned whith this problem could post their infos here. Thanks in advance.
