Hello, group!
Thanks for being here, I have found so much help on this site and decided to finally become a member.
I am new to valve amplifiers and have been playing around with the readily available Jan 6418 tube. I really dont know what I am doing so sorry for any dumb questions.
I have recently made some amps for my crystal radio receivers (using high z phones) which have worked great, however, when I plug my guitar in, the sound is very weak and distorted.
Another problem is that 3 of these tubes in tandem with a matching transformer can barely drive a speaker. I know that I must be doing something wrong because others have had better results. the schematic i used will be attached, i simply run a few one after the other.
I am running 1.45 v on the filaments and 30v on the plates.
Do I need to run a voltage amplifier tube before the 6418? Do I need to run a bigger power amplifier tube after? Also, can I squeeze a little more out of the 6418, by say, running the heaters at 1.5v and the plate at 36v?
Thanks in advance..
