Balance adjustment without distortion meter - Set VR01 to 2/3 position from max. point & Set VR02 to 2/3 position from min. pointMine doesn't have VRO3-4-5-6. There are resistors in those places. VRO1-2 NEED SCOPE. Without scope VRO1 should be set at 2/3 from max. VRO2 to be set at 2/3 from min.
You really don't have a lot of choice unless you can find NOS originals, the substitutes suggested, although overkill in respect of their basic specs, have the important metal tabs, (TO220 case) which is the same arrangement as the originals. There are other replacements with similar spec's like KSA1220A (PNP) & KSC2690A (NPN) - but they don't have the metal tab (TO126 case) - so your installation of these types needs to take account of this.Can anyone tell me if the link on the modern replacement is a good choice?
Thank you so much Hyperion.
