Analizor privind raportul de transformare (1974)

Recommended Posts

Buna ziua

 

Asa cum spune si titlu Transformer ratio analyser (Analizor privind raportul de transformare (1974))

Acum citeva zile am  rasfoit internetul, si am dat de acest proiect (instrument de masura ) din anul 1974, dar cred ca este si acum de actualitate, mai ales pentru cei care se ocupa cu constructia amplificatoarelor audio pe tuburi .

Am facut citeva teste pe transformatoare de iesire audio, privind raportul de transformare (calitatea materialelor folosite la  tole) o sa revin cu masuratori pentru urmatoarele  transformatoare de iesie  -INDEL- TANGO - TRANS RUSESC - PHILIPS -MULLARD . :multumesc
