{"product_id":"prs-hdrx-100-head","title":"PRS HDRX 100 Head","description":"\u003cp\u003eThe HDRX 100 is the full-power HDRX: 100 watts from four EL34s through a custom Straight Edge 100-watt output transformer, made at PRS's Stevensville, Maryland factory. Its circuit follows a Hendrix amp that Paul Reed Smith and Doug Sewell examined in 2018, one said to have been used at Woodstock.\u003c\/p\u003e\n\u003cp\u003eChannels 1 and 2 are bridged inside the chassis, so the Bass Volume and Treble Volume blend into one sound without a patch cable, with shared Treble, Middle, Bass and Presence beside the high-mid gain switch and three-position bright switch. PRS notes the power supply and filament design keep hum and hiss very low.\u003c\/p\u003e\n\u003cp\u003eThere is no master volume, since amps of that era often had to double as a PA, and PRS recommends an attenuator. The HDRX 4x12 Cabinet is our pick to go under it. If 100 watts is more than your rooms need, the HDRX 50 Head is built to sit close to it.\u003c\/p\u003e\n\u003cp\u003eSPECIFICATIONS\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAMPLIFIER\u003c\/strong\u003e\u003cbr\u003eCountry of Origin: USA\u003cbr\u003eAvailable Configurations: Head Only\u003cbr\u003eWattage: 100\u003cbr\u003eOutput Transformer: Straight Edge 100 Watt Output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTUBES\u003c\/strong\u003e\u003cbr\u003ePower Tubes: (4) EL34\u003cbr\u003ePreamp Tubes: (3) 12AX7 \/ ECC83\u003cbr\u003eV1: Input\u003cbr\u003eV2: Cathode Follower\u003cbr\u003eV3: Phase Inverter\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCONTROLS\u003c\/strong\u003e\u003cbr\u003eGlobal Controls: Treble, High Mid Gain Switch (on\/off), Middle, Bass, Presence\u003cbr\u003eFront Panel Controls: Channel 1 Controls - Bass Volume Channel 2 Controls - Treble Volume, Bright Switch (Off, Bright 1, Bright 2) (Channels 1 and 2 are internally bridged)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCONNECTIONS\u003c\/strong\u003e\u003cbr\u003eInlet: Fused Power Inlet (IEC)\u003cbr\u003eExtension Speaker Jacks: 5\u003cbr\u003eOhm Switching: (2) 4 ohm \u0026amp; (2) 8 ohm parallel, (1) 16 ohm\u003cbr\u003eBias: Adjustable with Monitoring Jacks\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHARDWARE\u003c\/strong\u003e\u003cbr\u003eCovering: Black Tolex\u003cbr\u003ePiping: Black\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDIMENSIONS\u003c\/strong\u003e\u003cbr\u003eAmp Width: 21.5\" (54.61 cm)\u003cbr\u003eAmp Depth: 10\" (25.4 cm)\u003cbr\u003eAmp Height: 10\" (25.4 cm)\u003cbr\u003eAmp Weight: 40 lbs (18.14 kg)\u003c\/p\u003e\n","brand":"PRS","offers":[{"title":"Black Tolex","offer_id":47769315377236,"sku":"107592::ST--:","price":4799.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1220\/7188\/files\/HDRX_100_Head_sq.jpg?v=1791389156","url":"https:\/\/lauzonmusic.com\/products\/prs-hdrx-100-head","provider":"Lauzon Music","version":"1.0","type":"link"}
