I am contemplating an amp build. (I am still in the homework stages.) I am trying to stay as close to the original 5F1 design which calls for an;
Output Transformer that is 8 watts and 4 ohm
Power Tube is a single 6V6.
Speaker is an 8” 4 ohm
My question is about the speaker size and wattage. It looks like none of you ever leave the low watt 8” speaker in tact. Why? Is it a volume issue or a sound issue? I am not looking for volume out of a champ.
What is the “preferred” speaker upgrade? & Why?
When upgrading the speaker, I would expect the OT to need to be upgraded as well. However when I look at OT’s greater than the 8W, 4ohm, they list it as being for a two 6V6 amp. Would you have to add a 6V6 power tubes to go from 8W, 4ohm
Hoffman #022921 to the 12W, 8ohm
Hoffman #022905?
Also, I have a question about amp wattage VS speaker wattage. Isn’t it preferable to keep your speaker max wattage to the same ballpark as your Amp wattage? (ie. no 50 W speakers on an 8 W head.) Is there a table or a fast and tried rule?
Thank you for reading this far.
