Figure 2-2. Bias Transformer Primary Connections
for 208Vac Operation (Model 6259B, 6260B, 6261B,
6268B, and 6269B) and 115Vac Operation
(Except Model 6269B)
b. Unsolder wire from circuit breaker A5CB1
connected to "230V" terminal of bias transformer
A3T2 and solder it instead to "208V" terminal of
transformer (see Figure 2-2 B). Leave wire from fan
B2 (not used in 62599) soldered to “230V” terminal.
c. Re-install RFI assembly by reversing pro-
cedure of Step (a).
d. Unsolder wire connected to terminal 5 of
power transformer T1 (see Figure 7-4) and solder it
instead to terminal 4 of transformer (see Figure
2-3 B).

Power Transformer Primary
Connections for 208Vac and 115Vac Operation
. (Model 6259B, 6261B, and 6268B)
2-19 CONNECTIONS FOR 208 VOLT OPERATION
(Model 6260B and 6269B: Option 027)
2-20 To convert Model 6260B or 6269B to operation
from a 208Vac source, taps on the power and bias
transformers must be changed as follows:
a. Perform Steps (a) through (c) of Paragraph
2-18.
b. Unsolder wire connected to to "230V” terminal
