Another Aiikido preamp using 12SN7 tubes (right side). This is actually my 1st tube build, got this as a kit from sir TonyT way wayback. Kaso after assembly maingay, lakas ng humming at dagundong pag tap mo sa case. I tried to rebuild and change some components with same results, this was a few years back at dami ko pa naka lineup na DIY and work so this was shelved, until this Monday naghahanap ako components sa stash ko nahagip ito ng mata ko so nailabas siya sa baul. After checking everything is still in order, voltages are right, I rewired the inputs and output then put a new set of tubes, and to my surprise all is well and good. The culprit was a pair of tubes that may have reached the end of life, RCA kasi at ganda ng tunog dati netong pair nato at parati ko gamit. Hanap pa pala ng knobs para sa volume at input selector
Ito na siya singing with my Darling SET amp and my DIY Human speakers. Hindi naka properly setup kasi tests jig ko na rin muna sila.
