since it is my first post here let me say hello to all users in this forum!!
and sorry for any spelling errors since english is not my native language !
i am strating to assemble a tube amp based on the schematic found here:
Five Tube Stereo Amplifier
i already have ordered all the parts and started the assembly using an old technics tuner case as the chassis. it is getting very preety and as i wait for the final parts to arrive i am still learnig investigating ans still have a few doubts that i hope you guys can help me with:
i am using a transformer with secondary of 340-0-340 instead of 300-0-300
do you think this will be tolerable or do i have to alter the dropping resistor/choke to lower the voltage?
also the designer says that the OT primary impedance is 3300ohm...isn't this a very low value for a 6v6? i have read that most 6v6 OTs are in the range of 5000ohm....following advice on another forum somebody told me to just buy an OT rated for use with single ended 6v6 amp so i ordered 2 of these
Output transformer for Fender Champ 5F1 or 5E1 Valve Audio Guitar Amplifiers 6V6 | eBay
will post pictures of the chassis and build progress soon
best regards
