5R4GYB RCA HARRISON T9 ENVELOPE
On offer today we have one of the short form T9 enveloped RCA 5R4GY - these often found use in Collins 516 power/control unit courtesy of their short form envelope but they loose nothing in performance over their ST19 colleagues. On test this device shows good emission and good matching between each diode section - an excellent RCA device at a keen price - forget prejudice and fit this and reap the reward of a sag free HT with commensurate sonic performance.
