Claymore come in six version of issues. Iss 1 With Hitachi H-Pak FET's, these become obsolete. Fitted with a MC stage I was not happy with so scraped it. Iss 2 With Toshiba MOS FET's but still no MC stage Iss 3 As Iss but with a plug in feature for MC stage Iss 4 Upgraded to a better Toshiba MOS FET's Iss 5 As above but now fitted with Elna Audio caps Iss 6 As above but with built in MC stage.
What the upgrade gives you and your Claymore. All electrolytic capacitor upgrade to 105C from 85C The 4 main PSU caps Upgraded from 4,700uf each to 10,000uf each The signal path capacitors upgrade for bi-polar caps The 4 3Amp diodes in the PSU upgrades to 6Amp diode with a lower Vf The bright Red LED changed to Green All 4 MOS FET's from 8 Amp and RdsOn of 1.8R changed for 25Amp+ at 50mR device and rated at 150W each and not 100W max. All other duff parts such as Volume, Selector switch and other sundry such as hardware are also fixed.
Post and packing are up to you but I will want them packed very well. You well also need to pay for collection and thus insurance.
