| 5D3 Deluxe as a harp amp...
...as suggested by Gerald Weber some time back. Changing the preamp power supply dropping resistor value, increasing coupling cap value, using a pot in place of the 56k resistor in the phase inverter, upping the cathode bypass cap value...any thoughts, or has anyone tried these mods? I have a 5E3 build, and am thinking of redoing it just to see how well it may work. TIA-

Personally I like dropping the power in the preamp section – I rather drop the power and have a 12AT7 than running a 12A-Y/U- 7 with normal power. Changing the caps to 0.1 is cool as well (but in a 5E3 they are 0.1 already. Regarding the phase inverter : It does work ! But not as described in his article – sorry. But hey if you got the 5E3 it should take you no time to test it ! I’m sure a lot got to do with speakers, personal taste, etc. Good luck ! Hope to hear your side of the story ; )

| 5D3 for harp...
Hi Morton- well, I received the few parts I neede to convert the 5E3 to the 5D3 today, and I have a variety of speakers on hand, so with any luck, I'll have something to post in a week or two (holidays...). Check out the other thread I have here discussing a design of Bruce Collins', which I'd REALLY like to try out. Thanks for your input, and happy holidays.
