Capacitor values for the 8 ohm Hiraga network:

Hirga specified capacitance values for the 8 ohm crossover: C1 = 36 uF, C2 = 19 uF, C3 = 1.7 uF

It is difficult to find capacitors with capacitance
values exactly matching the Hiraga values. I have substituted 40 uF for C1, 18.75 uF for C2, and 2 uF for C3. This combination
sounds wonderful. Frequency response calculations using the Spice program show little difference in frequency response
between the values specified by Hiraga and the values that I have substituted.

Recommended C1 configuration:

Parallel combination of 2 each Type 2, 20
uF, 600 volts AC capacitors gives 40 uF. Four each capacitors for stereo pair @ $60 each, $240 USD

Recommended C2 configuration:

C2, Level 1: Type 1 capacitors, 12.5 uF, 370
volts AC. Two capacitors in series gives 6.25 uF. Combine the two capacitors wired in series and then paralleled with
single capacitor gives 18.75 uF. Six each capacitors for a stereo pair @ $25 each, $150 USD

C2, Level 2 (subtle improvement over Level 1): Type 1 capacitors, 12.5 uF, 370 volts AC. Assemble three sets of two
capacitors in series. Combine the series sets in parallel to get 18.75 uF at 740 volts AC rating. Twelve each capacitors for
a stereo pair @ $25 each, $300 USD

Suggestion: Start with C2 Level 1, go to C2 Level
2 as the budget permits.

Recommended C3 configuration: One Type 3, 2 uF, 660 volts
AC per channel. Two required @ $25 each, $50 USD.

Total price of capacitors for a
stereo pair: With C2 Level 1: $540 USD; with C2 Level 2: $690 USD

Shipping
weight, all capacitors for stereo pair: 9 pounds with C2 Level 1, 11 pounds with C2, Level 2

Capacitor values for the 16 ohm Hiraga network:

Hiraga capacitor values: C1 = 18 uF, C2 = 10 uF, C3 = .82 uF

It is difficult to find capacitor valued exactly matching the Hiraga values. I recommend using 20
uF for C1, 10 uF for C2, and 1 uF for C3. Frequency response calculations using the Spice program show little
difference in frequency response between the values specified by Hiraga and the recommended values that I have substituted.

Recommended C1 configuration: Single Type 2, 20 uF, 600 volts AC capacitor
per channel. Two required for stereo pair, at $60 each, $120 USD

Recommended C2 configuration:

C2 Level
1: Two Type 2, 20 uF, 480 volts AC capacitor per channel, wired in series to get 10 uF with 960 volts rating. Four required
for a stereo pair, at $48 each, $192 USD

C2 Level
2 (subtle improvement over Level 1): Type 1, 12.5 uF, 370 volts AC capacitors, three in series gives 4.2 uF; 2 in series gives
6.25 uF; combine series strings to get 10.45 uF. Ten required for streo pair, at $25 each, $250 USD.

Recommended C3 configuration: Still testing; consult with Pete: peteriggle@msn.com

Total price of all capacitors needed for
a stereo pair: $442 USD, plus price of C3 capacitors.
