Can someone advise on  the correct way to solder the kind of voltage regulators found in amps ? ie; TDA 2050. Some suggest earthing the body to ground and then there is the question of the correct soldering iron temp.

Does anyone know the value-and purpose, of D5 and D6 Diodes on a guitar amp curcuit board?

There are many out there who describe modelling amp voicings as clinical or synthetic or even phoney.
It could be true in some cases. However the alternative, which is to buy the real deal-valve amps, is very expensive. A Marshall,Vox AC,Fender and Mesa alone can amount to several thousand pounds or dollars;you then need space to store the things. I own a small modelling unit and the sounds,while not capturing every nuance of what they imitate, come across as genuine enough for me.

 I need a replacement transformer for a Vox hybrid amp(non-modelling). it has 4 output leads plus earth. I should point out that UK Vox distributor KORG cannot supply such a thing
The top is marked 066-CVE GT 0006. Whether that means anything-i dont know. the amp curcuit is regulated by a ST electronics TAD2050 chip with an output rating of 32watts.

Is a transformer like that available to buy or would it have to be re-wound?
